> **NOTE on OPS243-A-W (WiFi version):** The standard **OPS243-A** (USB only) is strongly recommended. The WiFi module on the OPS243-A-W drives the internal UART receive line, preventing direct connection to the Raspberry Pi GPIO UART (Layout A). However, if you already have the WiFi version, it can still be used over USB with a powered USB hub (Layout B) when paired with the IWR6843 angle radar.

## Sound Trigger (for Rolling Buffer Mode)
The sound trigger detects club impact to precisely time radar captures. Essential for spin detection via rolling buffer mode.
-> **Optional path, not merged yet:** [PR #221](https://github.com/open-flight/openflight/pull/221) adds an opt-in `--trigger hardware` mode in which the OPS243 fires the rolling-buffer dump from its own internal speed trigger, with no SEN-14262 in the loop. It requires OPS243-A firmware v1.3.1. If it lands and your OPS243 can be updated to that firmware, the parts in this section become optional. Until then the sound trigger is the supported trigger and stays in the totals.

-| **DC adapter for the X1202 (5.5 × 2.1 mm barrel, center positive, 6-18V, 3A or more)** | Feeds the X1202 through its barrel jack instead of USB-C, which is the better input for a cased build: no USB PD negotiation to fail and no USB-C extension to sag. The X1202 accepts 6-18V DC on that jack and converts it to the 5.1V 5A the Pi 5 needs while also charging the cells. Geekworm's stated requirement is a current, not a wattage: "6-18Vdc, ≥3A", with charging at up to 3.2A into the cells; it publishes no watt figure. Where the power goes: the Pi 5 can draw up to 25.5W (5.1V × 5A) with both radars on its USB budget, and charging adds up to about 12W when the cells are low, plus converter losses. So the same 3A buys different things at different voltages: at 12V (36W) it runs the Pi at full load and charges at the same time, which is why Geekworm's own adapters are 12V; at 9V (27W) it runs the Pi but charging slows under load; at 6V (18W) it cannot carry a full Pi load and the cells drain while plugged in. **Check the amps against the voltage** rather than treating "6-18V" as "any adapter": a little over 25W is enough to run the Pi, not to run it and charge at full rate, and 12-18V at 3A or more covers both. Examples: MEAN WELL GST36 (12V 3A; GST36U12-P1J US plug, GST36E12-P1J EU plug, both at Mouser) or Geekworm's own PSU60 (12V 5A, also sold as an Amazon bundle with the X1202).

Adafruit showed the 1152 out of stock when checked and its Amazon listing (B00SK6M36U) as unavailable; Mouser's stock is unverified | [Mouser (1445)](https://www.mouser.com/ProductDetail/Adafruit/1445?qs=GURawfaeGuAOIArgy7Ph4w%3D%3D) / [Mouser (1152)](https://www.mouser.com/ProductDetail/Adafruit/1152?qs=GURawfaeGuAkPRIbdozo3A%3D%3D) / [Adafruit](https://www.adafruit.com/product/1445) | ~$6 |
+| **DC adapter for the X1202 (5.5 × 2.1 mm barrel, center positive, 6-18V, 3A or more)** | Feeds the X1202 through its barrel jack instead of USB-C, which is the better input for a cased build: no USB PD negotiation to fail and no USB-C extension to sag. The X1202 accepts 6-18V DC on that jack and converts it to the 5.1V 5A the Pi 5 needs while also charging the cells. Geekworm's stated requirement is a current, not a wattage: "6-18Vdc, ≥3A", with charging at up to 3.2A into the cells; it publishes no watt figure. Where the power goes: the Pi 5 can draw up to 25.5W (5.1V × 5A) with both radars on its USB budget, and charging adds up to about 12W when the cells are low, plus converter losses. So the same 3A buys different things at different voltages: at 12V (36W) it runs the Pi at full load and charges at the same time, which is why Geekworm's own adapters are 12V; at 9V (27W) it runs the Pi but charging slows under load; at 6V (18W) it cannot carry a full Pi load and the cells drain while plugged in. **Check the amps against the voltage** rather than treating "6-18V" as "any adapter": a little over 25W is enough to run the Pi, not to run it and charge at full rate, and 12-18V at 3A or more covers both. Examples: MEAN WELL GST36 (12V 3A; GST36U12-P1J US plug, GST36E12-P1J EU plug, both at Mouser) or Geekworm's own PSU60 (12V 5A, also sold as an Amazon bundle with the X1202). Never connect the DC jack and the USB-C input at the same time | [Mouser (EU plug)](https://www.mouser.com/c/?q=GST36E12-P1J) / [Mouser (US plug)](https://www.mouser.com/c/?q=GST36U12-P1J) / [Amazon (PSU60)](https://www.amazon.com/dp/B0BDF89DCB) | ~$15 |
| **InnoMaker OV9281 global-shutter camera** | High-speed monochrome camera for experimental vision work. Camera software is not enabled in the production kiosk path | [Amazon](https://www.amazon.com/dp/B09WTP5GZH?th=1) | ~$30 |
-| **Adafruit DS3502 digital potentiometer** | I2C-controlled 10K digital potentiometer (STEMMA QT / Qwiic). Intended for the SEN-14262 `R17` gain trim: installed in series with a fixed 37kΩ resistor it gives a software-adjustable 37-47kΩ range, so preamp gain can be tuned from code instead of desoldering and swapping a fixed resistor. **Not yet built or tested** — no code drives it, and [sound-trigger-wiring.md](../build/sound-trigger.md) still assumes a soldered R17. Wiring plan: further down the same Qwiic chain as the inclinometer (Pi → Qwiic-to-Dupont → LIS3DH → Qwiic-to-Qwiic → DS3502), so it takes no extra Pi header pins. Research item for the sound-trigger path only; moot if the [PR #221](https://github.com/open-flight/openflight/pull/221) internal trigger replaces the sound trigger | [Adafruit](https://www.adafruit.com/product/4286) | ~$5 |
-| **STEMMA QT / Qwiic-to-Qwiic cable (for the DS3502)** | The link from the LIS3DH's second STEMMA QT socket down to the DS3502, so the digital potentiometer joins the same I2C chain without taking any Pi header pins. Only needed if the DS3502 is fitted. Sold in 50-400 mm lengths; 100 mm (Adafruit 4210) is right if the DS3502 sits beside the LIS3DH on the enclosure floor, which is the sensible place for it: the two wires from its wiper to `R17` on the sound detector then run to the front half of the case (~175 mm straight, ~300 mm routed, so they come out of the same 300 mm jumper pack) rather than the I2C chain doing so | [Adafruit](https://www.adafruit.com/product/4210) | ~$1 |
+| **Panel DC jack with leads, 5.5 × 2.1 mm (DC route)** | The socket in the shell's rear DC hole. Mouser: Tensility 10-03609, an overmoulded panel jack on a 305 mm 18 AWG lead, rated 7.5 A, M11 × 1.0 thread with the nut and lock washer fitted from inside, for panels 1.5-4.5 mm thick. The shell's Ø12.5 mm hole is 1.3 mm over its thread and its Ø13.5 mm head has flats at 9.8 mm, so it clamps but shows a sliver of hole at the flats. Amazon: the pre-wired DC-099 style kits with a 12 mm thread fit the hole as drawn, such as the [6-set](https://www.amazon.com/dp/B0DP6MNQQB) the enclosure's reference model was made from (150 mm 20 AWG leads) or a [10-pack rated 5 A](https://www.amazon.com/dp/B08F26JJKM) with 150 mm 18 AWG leads; the [DaierTek set](https://www.amazon.com/dp/B0BD46CP5Y) adds pre-wired 5.5 × 2.1 mm plugs for the barrel-jack option. Tensility's other 2.1 mm lead, 10-02878, has a Ø10.8 mm thread but only a Ø12.5 mm flange, the same as the hole, so it is not the one to buy. Mouser's Tensility listing is unverified from here; Tensility sells direct at $6.74 | [Mouser (search)](https://www.mouser.com/c/?q=10-03609) / [Tensility](https://www.tensility.com/products/10-03609) / [Amazon (6-set)](https://www.amazon.com/dp/B0DP6MNQQB) | $7-10 |
+| **Wago 221-412 lever connectors, ×2 (DC route, header option)** | Two-conductor lever splices for 24-12 AWG that join the jack leads to the XH lead without tools, one per conductor. Any two-way 221 does; the inline 221-2411 is the same clamp in a straight-through body. The barrel option below needs none | [Mouser (search)](https://www.mouser.com/c/?q=WAGO%20221-412) / [Amazon (bag of 10)](https://www.amazon.com/dp/B072PT3JNL) | $1 |
+| **UPS end of the DC route: JST XH 2-pin lead (header option) or screw-terminal barrel plug (barrel option)** | Header option: the plug for the X1202/X1206's `XH2.54-2P` DC input. One pair from the Adafruit 1152 pack in the button row is exactly this (XH plug, 20 cm of 22 AWG, quick-connects cut off), so nothing extra is needed if you have that pack; otherwise Adafruit 4872 is a matching XH-compatible plug-and-socket pair with 20 cm leads, but its 26 AWG wire is thin for the 3 A the input can draw, so prefer the 1152 pair. Barrel option: Adafruit 369, a 5.5 × 2.1 mm plug on a two-way screw-terminal block marked + and −; the jack leads screw straight in, so no Wagos, and it goes into the UPS's own barrel jack.

-## Cable Lengths (Enclosure v2)
+## Cable Lengths (Enclosure v3)
The parts rows above already say which length to buy; this section is the
measurement behind them, for anyone changing the enclosure or the wiring.
Ordinary builders can skip it.
-Measured cable runs on the v2 enclosure
-
-Measured on the 2026-09-09 Onshape export of the v2 back housing (the
-`back-pi-display2` variant, for the Touch Display 2), from the insert pockets
-and standoffs that locate each board: the OPS243 on the 67 × 82 mm pattern at
-the bottom right, the IWR6843LEVM on the 48.5 × 49 mm pattern at the bottom
-left, the X1202 with the Pi stacked on it over the battery hatch, the LIS3DH on
-its 21 × 13 mm pad on the floor to the left of that stack, and the camera on
-the top shelf. The sound detector's position comes from the build, not the
-CAD: it is screwed to the back of the display in the front half, top-right of
-the case when closed, and its depth is assumed. Straight-line is
-connector-to-connector; routed adds the bends around the Pi/UPS stack and over
-the rim. Buy the length in the last column.
+Measured cable runs on the openflight-enclosure v3 case
+
+Measured on the v3 CAD in the
+[openflight-enclosure](https://github.com/open-flight/openflight-enclosure)
+repository (`Open-Flight-Monitor-3.step`; the 2026-09-15 release and the PR #10
+re-layout merged on 2026-09-21 share the same shell and mounts) from the features that
+locate each part: the OPS243 and IWR6843LEVM models on the radar front, the
+mic hole and the OV9281 on the camera strip, the X1202's 89 × 58 mm mount
+pockets on the rear wall, the three Adafruit bays on the floor, the Display 2
+bezel, and the three cutouts in the rear recess wall (the Ethernet coupler at
+the left, a Ø12.5 mm hole in the middle that the CAD gives to the DC jack, and
+a Ø12.5 mm hole at the right for the power button). The Pi, UPS, sound
+detector and display are not in the CAD, so their connectors are placed from
+their own drawings: the X1202 from Geekworm's interface photo (DC jack and
+`XH2.54` DC input at its top-left corner, the external-button header `PSW` at
+its bottom-left), the Pi 5 portrait on top of it with the USB ports up, the
+GPIO header along its left edge and the DSI/CSI connectors along its right
+edge, and the Display 2's FPC connector at the bottom centre of the panel.
+Treat those as ±15 mm. Straight-line is connector to connector; routed is a
+right-angle path along the walls plus the plug bodies. Buy the length in the
+last column.

-Both radars hang from the tops of their standoffs with the antenna side facing
-the back wall, so their connectors point at the floor and the wires plug in
-from below; the Pi header is level with the rim. The halves are held together
-by through-bolts, so servicing means lifting the front half off and laying it
-beside the back half, which adds ~100 mm to the two detector runs. That, not
-the closed-case distance, is why the detector wires are 300 mm.
+| OPS243 UART + 5V + GND (4 wires) | OPS243 `J3` (radar front, bottom right) → Pi GPIO header (rear wall) | ~60 mm | ~115 mm | 150 mm works; the 300 mm pack covers it |

+
+The fronts unscrew from the shell (radar, then camera strip, then screen), so
+servicing means lifting the camera strip off with the sound detector still on
+it and laying it in front of the case, which adds ~100 mm to the two detector
+runs. That, not the closed-case distance, is why the detector wires are
+300 mm.
+
+Both Ø12.5 mm rear holes are the same size, so which one takes the button and
+which the DC jack is the builder's choice; the CAD puts the DC jack in the
+middle. With the Adafruit 1152 leads, put the button in the middle hole
+instead: it is the shorter run, and the jack lead is the easier one to buy
+long.

+How the filament estimate was made
The enclosure filament line is an estimate from the CAD, not a slicer figure,
and it assumes **PETG**, not PLA: the case lives outdoors in the sun, and PETG
holds up to UV and to a hot car far better than PLA (it softens at ~80 °C
against PLA's ~60 °C), while still being a stock spool everywhere and an easy
-print on an enclosed printer such as the P1S. The v2 back housing is a
-195 × 248 mm tray, 52 mm deep inside, with 3.5 mm walls, a 2.5 mm floor,
-57 mm radar standoffs and four corner bolt columns: about 300 g at two walls
-and 10 % infill. The front half (the display frame) is ~170 g, the kickstand
-~70 g, the battery hatch and the two kickstand pegs ~30 g together, and
-supports plus a purge line take the print to roughly 600 g of PETG (a few
-percent more than the same parts in PLA), two-thirds of a 1 kg spool. At
-$20-25/kg that is ~$15. Replace it with the sliced weight once the v2 files
-are published. Heat-set inserts, screws and the kickstand ball plunger are in
-the enclosure repository's own parts list
