Missing details about buzzer

[Stampeder525]

In the documentation, as well as on the Oui-Spy site, the required materials only calls for a "3V PWM/Piazzo buzzer". I haven't been able to find details for anything more specific than that, but when I ordered some, I found that they were too small to fit on the custom PCBs. I ordered a different batch of 3V pwm buzzers and they were also too small. In pictures, the buzzer is clearly large enough to fit through both holes on the PCB, and covers the whole circular section designated for it. It seems like all of the listings I find for 3V PWM/Piazzo buzzers are for that smaller size.

Would it be possible to supply a shopping guide, or additional details on what specific size/measurements of buzzer is required for this?

You're generally looking for a 9 mm 2 pin 5 vdc buzzer common in Arduino sample kits. A few examples below.

@alteregonyc Thanks for the pointers! I'll check these out. I notice these are 5V buzzers although the build materials call for 3V. Will they still be a suitable replacement?

I can only report that the 5 v buzzer i had lying around works fine. I ordered the raw board and used a Seeed ESP-C3 I had lying around which worked fine once I made the documented change to switch the code line for the buzzer port on the C3.
