M5Dial: i2C voltage level, 3.3V or 5V?
-
Hi
Does anybody know the voltage level of the I2C interface on Port A of the M5Dial?
I want to connect a M5Dial with I2C with an Arduino Nano ESP32. Both use the ESP32-S3 which is running on 3.3V. But on the Port A connector of the M5Dial there is 5V. So I am confused.
Can I connect both boards directly (i.e. SDA, SCL and GND), or will this damage the Nano ESP32?
Thanks, nalom1

@nalom1 this 5v and ground there is to supply sensors/units but voltage levels for gpio are 3.3

@robski Thanks a lot
