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 breakout 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.
