First batch of 3104-01 ESPHome AUX AC PCBAs arrived, with cool looking (at least that is my opinion) black mat soldermask!
Some basic initial testing was done:
- supplying with 5V didn’t damage the PCB
- output of the regulator was stable at 3.3V
- it was possible to program the ESP32 over UART and later over WiFi
- communication tested with AUX AC device
- documentation on GITLAB updated with simple configuration,
Next and final step for this project sending the orders.
