Im having trouble connecting my ESP32 to my board im using the UART in the main board to connect my ESP32 but when i run the code the serial monitor says ESP32 not responding or not connected. My pin connections are
ESP32 Main Board
RX2 TX0
TX2 RX1
GND GND
anyone knows how to connect them together?

Connection with Serial is not possible. The RX and TX pins are not available to connect, unless you do a careful soldering yourself.

The only way is I2C (Qwiic) or SPI with the ESP32 running is "slave’ or “peripheral”. The Artemins only supports running as “master” or “controller”.

i already fix it, there is UART in the sparkfun main board i already have solder header pins on them. The fix for my problem is that you need to connect the SEL and GND on the main board to make the UART works
