There's a fork for the older Realtek Ameba chips (RTL8195AM / RTL8711BN)
Not sure what their plans are for the RTK8720DN.

According to the schematics, populate C15 with a “104” 0.1uF 0402 cap. https://github.com/mcauser/WEACT_F411CEU6/blob/master/docs/STM32F411CEU6_schematics.pdf SPI flash is not required, but it does provide more space. When building the firmware, you can pick how you want to use it. I am using an ext...

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 some...
Hi @ajocius, yes to both of those. I’m using the 4ch blue logic level converter in your link. The YS module does not support all IR protocols. It specifically listens for and transmits the NEC protocol. If you want to RX any remote, you can with a TL1838 IR receiver LED, but you’ll need to decode th...

Looks like new H7 variants of the MCUDev DevEBox. This is the similar F4Vxxx version: https://a.aliexpress.com/tYFolED6 I made a board def for it. https://github.com/mcauser/MCUDEV_DEVEBOX_F407VET6 I haven’t worked with H7’s before. If there are other H7 boards running MicroPython, should be pretty ...

Alternatively, if you swap that simple shift register with a display driver IC, such as the MAX7219, you can drop your resistor count to 1x and drive 64x LEDs, or many more of you chain a few ICs. Even supports brightness control in software. https://www.maximintegrated.com/en/products/power/display...
Here's how I attempted to add the SigmaDelta peripheral: https://github.com/micropython/micropython/pull/5452/files It's a very simple peripheral, but shows you the pieces needed. The Pulse Counter peripheral is much more complex. https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/p...
