ESP32 GPIO14

GPIO14 / ADC2_CH6 / TOUCH6 / MTMS

Use with care - Fine for many uses, but check the warnings below first.

What GPIO14 can do

Digital input/output
ADC2 analog input (unusable while Wi-Fi is active)
Capacitive touch sensing
PWM output (LEDC)

Warnings for GPIO14

ADC2 unusable with WiFi

ADC2 is used by the WiFi driver. Any analogRead() on an ADC2 pin returns errors while WiFi is active. Use ADC1 pins (GPIO32-39) for analog readings when WiFi is on.

Must float at boot

This pin must not be driven LOW or HIGH by external circuitry at boot or the ESP32 may enter an unexpected boot mode.

Outputs PWM signal at boot. Can interfere with attached hardware.
