Explore the ESP-PROG board

The ESP-PROG board can be used to program a custom board that doesn’t have a FTDI inter-phase. The details can be located here. I connected a Pic0 board and the ESP-PROG using an Adafruit 6 pin AVR ISP breadboard adapter and 6 pin IDC cable. I was able to program the Pico by connecting the same pins from the ESP-PROG board to the Pico board as shown below.
