Project Description

Based on ESP_PICO, the control unit is equipped with SW3526 multi-protocol fast charging source with redundant power of 231W.

Communication group: 754881030

The basic functions have been completed and the program source files have been uploaded. The capabilities are generally limited and may not be perfect in some places. Please don’t complain. Children who have other ideas can freely express themselves based on this.

Software Description

⚫ Press the encoder without letting go → The programmer is powered on TTL (if the welding buzzer will sound for a long time)

⚫ Select the corresponding serial port and click Start to wait for the program to be burned. Just cut off the power and restart (provided there is no problem with welding!)
