 ## Hardware
-- Any ESP32 based board. (e.g. Wemos D1 mini ESP32)
-- Any DC-DC Step Down to 5V, because most ESP32 boards can't handle car voltages (~14V). (e.g. DC Power Shield for WEMOS D1 mini)
+- Any ESP32 based board. (e.g. Wemos D1 mini ESP32), doesn't work with ESP32-C*, -S*, -H* series, only with ESP32
+- Any DC-DC Step Down to 5V, because most ESP32 boards can't handle car voltages (~16V). (e.g. DC Power Shield for WEMOS D1 mini)
