Pin functions in bold font are the default pin functions in SPI Boot mode. For pins No.38 ∼ 42, the default function is decided by eFuse bit.
3
Power supply for GPIO33, GPIO34, GPIO35, GPIO36 and GPIO37 is configurable to be either VDD3P3_CPU (default) or VDD_SPI.
4
The pin function in this table refers only to some fixed settings and do not cover all cases for signals that can be input and output through the GPIO matrix. For
more information on the GPIO matrix, please refer to ESP32-S3 Technical Reference Manual.
