Description
This is an ESP32 programmer similar to an official ESP-Prog programmer device for ESP32 and ESP8266 modules from Espressif. It uses an CH340C chip and has an optional 3V3 regulator. There are no switches or JTAG support as in the original. The PCB is however designed so that it can be easily encased by using transparent heat shrink tube. More info can be found from link below.
