Arduino Nano BLE Sense 33 second serial port

Is there a simple method for adding a second (USB/RS232 preferred) serial port via a QWIIC interface?

It won’t be simple but you could program an an arduino to be a I2C slave and code it to translate I2C to serial and back.

Arduino has a tutorial you could probably bend to your needs.
