ESP32-S3 TWAI Pin Multiplexing

Postby jgbkhs » Mon Sep 15, 2025 7:41 pm

Just confirming as I am not able to see clearly via the documentation in the technical manual or module datasheets: Can the TWAI peripheral RX/TX pins truly be mapped to any GPIO pin whatsoever? Are there truly no restrictions?

You can indeed route them to any otherwise unused GPIO pin.
