ESP32-C3 GPIO5
GPIO5 / ADC2_CH0 / MTDI
Use with care
- Fine for many uses, but check the warnings below first.
What GPIO5 can do
- Digital input/output
- ADC2 analog input (not supported by ESP-IDF on this chip)
- PWM output (LEDC)
- RTC GPIO (usable in deep sleep, wake source)
- jtag
Warnings for GPIO5
ADC2 not supported
ESP-IDF no longer supports ADC2 on the ESP32-C3 because of a hardware limitation (unstable results). Use an ADC1 pin for analog reads.
