OLED Version DevKit ESP32 Watch Development Board

What is it
It is a ESP32 Watch development 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. What makes it special
