Warning

The D1 Mini ESP32 board may suffer from brown-out reboots if not powered adequately.

Note

(²) Because the board is developed for the D1-mini, you must only solder a row of 1x8 male pins to pads TXD-5V and RST-3V3 each.

Backlight Control~

To use PWM dimming on the Lolin TFT 2.4" you must connect the TFT-LED pin to either D1 or D2. D1 is recommended for backlight control and configured by default in the firmware.

TFT-LED PWM dimming

Warning

Do not use D3 for backlight control because it is already in use for touch!
Do not use D4 for backlight control because it is already in use for PSram on the ESP32-WROVER, also the D1-mini has D4 connected to the on-board LED and boot fails if pulled LOW
