This week, I had a go at building a DevKit for the ESP32-H2-MINI-1 module
This features some new things for me.
I’m going for an ESP32-H2 module this time. I’m a big fan of the ESP32 and it’s a very accessible piece of hardware thanks to Arduino and ESPHome. The H2 doesn’t have WiFi, instead relying on Zigbee/Thread radio.
It has a USB connector. To make this more accessible, I decided to give USB a try. The board can (hopefully) be flashed via USB, in addition to being powered. This meant a few more components were required. I made room for three LEDs too – 5v, 3.3v and one connected via a GPIO. Hopefully this will help with diagnostics.
I’m using the same MCP1700 power module. It can deliver 250mA of power, which is more than the peak demand of the H2. It wouldn’t work for WiFi modules, like the S3, but should be plenty for this.
The KiCad project is here at present: https://github.com/tomasmcguinness/matter-esp32-temperature-sensor/tree/main/Hardware/PCB
This board is a prototype now and completely untested. I’ve ordered some from Aisler, but they won’t arrive for a few weeks.
Stay tuned for updates!
