The CONNECT programmer is designed to enable extremely simple programming of boards based on ESP8266 and ESP32 microcontrollers.
It contains all the necessary electronics and logic so that programming can be done by connecting a USB cable to the CONNECT programmer and connecting the CONNECT programmer to the programming header. The electronics responsible for the timing and signal sequence are also located on the board so that the ESP microcontroller is put into bootloader mode.
The ESP programming header can be found on boards from Soldered that are based on ESP8266 or ESP32 microcontrollers and do not have a USB-UART converter. However, this programmer can also be used for any other ESP32/ESP8266 board.
