Hard to tell without more details about that extra module and how the two boards differ in wiring. Just speculating, but could it be that the extra module is mucking with GPIO(s) that are connected to vital things on the "custom board"?

What will happen if you have a 5V power supply connected to the VUSB port while the microUSB port is plugged into a computer? Will the Pyboard simply choose a power supply to use or will there be complications? I would advise against it. The +5V is typically produced by a voltage regulator (7805 or...

I would move the await asyncio.sleep(2) after the print() ... So you will get the temperature directly after start ;) From a cold boot the DHT sensor needs some time to stabilize and become ready. If you try to query it too soon after power on all you get is a ETIMEDOUT. You might be able to move t...

The AM2320 is an upgrade of the DHT22 / AM2302, and it supports both the old 1-wire interface and I2C. https://github.com/mcauser/micropython-am2320 Same goes for the tiny DHT12, which is an upgrade of the DHT11, and adds I2C too. https://github.com/mcauser/micropython-dht12 These could do with som...

Have you considered submitting a PR? I have. There is one small problem left with it that I still haven't figured out how to minimize. The whole thing is obviously based on two while() loops, the first waiting as long as both pins are unequal the requested levels, the second waiting until both are ...

There is nothing wrong with wait_ms = d.start() await asyncio.sleep_ms(wait_ms) d.receive() however if I were writing the device driver I'd either provide an awaitable receive method so you could write await d.receive() or make the class an awaitable class. Then you'd just have await d Either appro...

- use WSL, build hower you want (probably the least qualified as 'build on windows' given what WSL is)

The least qualified would be to install VMware or similar, create a Linux VM and build inside of that. But it does work great.

Hi, just mention that MicroPython introduced a separator option for binascii.hexlify function ...

Neat, thanks!

Note that the DS3231 has an "aging" register that can be used to adjust the TCXO slightly. The register is a signed 8-bit value and controls a capacitor array that is part of the crystal's load capacitance. The DS3231 documentation states that one LSB of the register equals approximately 0.1ppm spee...

The dollar sign at the beginning is one byte, the 'b' the second, followed by four bytes that don't have a corresponding ascii character and are therefore displayed in their \x representation.
