Voltage Levels for RX/TX pins on WiFi Lora 32(v2)

#1

I am using the WiFi Lora 32(V2) RX/TX pins on 5v levels. Is that recomended or am I risking damaging the board? What voltage levels do they accept, 5v levels or 3.3v?

hi,

We recommend you not to use 5V, ESP32 uses 3.3V level.

Long-term 5V voltage may damage the ESP32 chip.
