<![CDATA[PORT C with Core2 + M5GO Battery Bottom2 : 5V UART OK ?]]>Hi there

I've a Core2 with a M5GO Battery Bottom2 which exposes Serial2 (pin 13 and 14) on PORTC as well with 5V and GND. This is great to connect to a 5V UART module but I can't find in the specifications if the Rx pin on PORTC is OK with 5V

I google searched this but could not find any suitable M5Stack blessed documentation.
Any clue ?

thx

As for the Rx pin on PORTC, it's essential to check the specs to be sure about that 5V compatibility.

RX and TX on Port C are directly connected to ESP32 GPIO13 and GPIO14 and therefore 3.3 V only. Bottom2 schematics is here.

Thanks
