About this item

  • ESP Prog is a development Debugger, which has the functions of automatically downloading firmware, serial communication, JTAG online debugging, etc
  • The automatic firmware download and serial communication function are applicable to the ESP8266 and ESP32, while the JTAG online debugging function is applicable to the ESP32
  • ESP Prog is simple and convenient to use and can be connected to a computer with just one USB cable. The computer can recognize the two ports corresponding to the download function and JTAG function
  • The ESP-Prog can be connected to the user board using cables, and the connector can choose 2.54 mm and 1.27 mm spacing. The connectors for Program (6-Pin) and JTAG (10-Pin) need to be placed in the corresponding order on the user board
  • Both interfaces of the ESP-Prog can be powered by 5V or 3.3V through the Pin Header, which has strong power compatibility


The development board is a circuit board for embedded system development, including a series of hardware components such as a central processing unit, memory, input device, output device, Datapath/bus, and external resource interface. The development board is for beginners to understand and learn the hardware and software of the system. At the same time, some development boards also provide a basic Integrated development environment, software source code, and hardware schematic diagram. Common development boards include 51, ARM, FPGA, and DSP development boards.

This is a very nice tool for development and debugging ESP32 projects. I believe it could also help with customizing products (often "smart home" products) that use ESP8266/ESP32 if the board happens to have a functioning JTAG interface.

I've had a few instances of getting an Espressif devkit into a "non-bootable" situation and nothing I've been able to do using the onboard usb interfaces allows me to recover the hardware. On a whim I pick this up and have been able to get those boards back into my collection of working MCU's by connecting to them directly via the hardware JTAG interface. This has been a life saver when it comes to recovering these bricked boards.I have not really used it for anything other than direct JTAG program recover as I prefer to use other methods for flashing in my workflow.The printed text is easy to read and the board quality is better than other PCB's that I've encountered.

The included ribbon cable is the mini size (I think 1.27mm) instead of the standard 2.54mm--which is actually nice. I have extras of the standard sitting around, but very few of the small ones.It does not have any other connector to fit directly into the ESP8266/ESP32, so you'll have to figure that out if you don't already have an adapter board or breakout pins on your module. In a pinch, regular Dupont jumper cables will fit into the 2.54mm pins, no need for IDC ribbon cables.It uses the FT2232HL chip. You can download FTDI VCP drivers from the FTDI website if you don't already have it. I'm using Zadig also, and it works well with PlatformIO.
