Question aboutSuper Mini ESP32-C3?

Postby Hobby65 » Mon Oct 16, 2023 4:29 pm

Hello,
i want to use a SuperMini ESP32-C3 board. I found different informations about the I/O Pins. Can someone tell me what pins can
someone use as digital input or output pins? What pins can I use as interruptpins?
This is the board: https://de.aliexpress.com/i/1005005951597048.html .
Many thanks for every answer

See the C3's datasheet: https://www.espressif.com/sites/default ... eet_en.pdf
You can use all the pins on the board labelled GPIOx as digital input or output, and every GPIO pin can be used to trigger interrupts.
There are a few restrictions (see datasheet): GPIO9 is used as a 'strapping pin' upon reset (wired to the 'BOOT' button), and GPIO4-7 are used by JTAG if you want to use an external JTAG debugger.
