Re: DHT22 or AM2302 Sensor with micro:bit

DHT11, DHT22 and AM2302 only support the 1 wire interface. I haven't tried using one with a micro:bit yet. If you switch to a DHT12 or AM2320 (roughly same price), you can use their more user friendly I2C interface. You could try porting these to the micro:bit. You may need to change some method nam...

Re: Module for DHT22 temperature/humidity sensor

IMHO, swap the DHT22 for a AM2320.
It's a newer version of the DHT22 with dual interface 1-wire + I2C.

I even wrote a library for it:
https://github.com/mcauser/micropython-am2320

The AM2320 is around $1 cheaper than the DHT22 on AliExpress.

Well done! Very nice! Let us know when it's on your tindie and I'll grab one. I'll have to start coming up with ideas for ... µGames .

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

The VCC-GND F4 VET6 (mini) uses a 25MHz system crystal, and the black F4 VET6 uses an 8MHz system crystal. Both use a 32.768KHz RTC crystal. Note the different HSE_VALUE values: https://github.com/mcauser/VCC_GND_F407/blob/master/stm32f4xx_hal_conf.h#L102 https://github.com/mcauser/BLACK_F407VE/blob...
