Using all GPIO's on ESP32-C3

Postby Jan-Petter » Thu Mar 24, 2022 12:24 pm

We will use a ESP32-C3FH4 in a project. We will not have a external flash. Is it possible to use all Gpio's including the ones dedicated to flash SPI as plane I/O's?

No. Internal flash still occupies some GPIOs. See the datasheet for more info.
