Adding support for ESP32-H2 #68

Closed conradopoole closed 5 months ago

conradopoole commented 6 months ago

This is an FYI on something I have been working on. I wanted to create a Matter Thread version of the ratGDO boards, so I decided to design one in KiCad. Granted we do not have a matter thread version of ratGDO but I plan on trying to port it using esp-matter and creating it as a LOCK + Light matter device.

Based on the ESP32-H2 chip and more precisely on the ESP32-H2-MINI-1 module. While working at it I also decided to add a buck converter so that it can be powered from either the USB-C port or an external power source between 12V and 24V, like the backup battery present in some GDOs.

Let me know what you think, I will be sending this revision to production soon, so hope to have the schematics and PCB validated soon.

Dimensions are around 48mm by 49mm. Screenshot of the 3D render below.

Looks good mate. I have no exposure to Matter so I can't really comment on that side of it but happy to host everything here!

My only feedback is the silkscreen naming of "RatGDO", since that might be trademarked by Paul (or at least cause confusion about if this is a Paul Wieland/ratCloud llc product).

I thought I heard there were stability issues with using wifi and thread/matter on the same chip at the same time - most espressif examples use the h2 as a network co-processor? I have no empirical basis for this though…

Well, the ESP32-H2 doesn't have WiFi at all, but even if we used the ESP32-C6 that has both WiFi 6 and Thread, you would use one of the two radios not both at the same time.

Please come back once this is tested and working so we can raise a Pull Request.
