OLED/TFT Color DevKit ESP32 Watch Development Board

What is it?

It is a ESP32 Watch development board. There are two versions: OLED version and TFT color version. Both version share the same bottom board.

Why did you make it?

This product was planned at the same time of deauther wristband. I learned a lot of experience from deauther wristband and I knew ESP32 is a better choice for a "Watch".

The break ou pads are also designed to connect different sensors.

TX/RX could be used to communicate with computer or other control board.

17/16 is IIC port could be connected with RTC module or other IIC sensors.

SVP/SVN could input ADC signals.

25/26 could output DAC signals.
