How to power 5V sensors

[cdupont]

Documentation to update in order to explain how we can power 5V sensors, such as the HC - SR04.

When powering with USB, 5V is provided as VCC (Input Voltage). Can you confirm @mojtaba-esk ?
You can use the VCC pin.

I think the pin is labeled "VIN". @mojtaba-esk It could be renamed "5V" in the next version for more clarity (it's like that on some Arduinos).

In this case, the red wire should go on VIN instead of VCC. I wonder if the "trig" and "echo" wires should go on high voltage pins also (M8 and M9).

VIN is actually an input pin for input voltage. theoretically it can be more than 5V which is regulated to 3.3V and in power optimization configuration, it can be as low as 3.3V where the regulator is bypassed.

Oh, sorry. So is there a pin in 5V?

[mojtaba-esk]

No, but VIN can be used as 5V if you power on the board via USB port.
