Function: 1. ESP-Prog is a development and debugging tool with automatic firmware download, serial communication, JTAG online debugging, and other functions. The automatic firmware download and serial communication functions are available for ESP8266 and ESP32 platforms, and the JTAG in-circuit debugging function is available for the ESP32 platform. 2. ESP-Prog is easy to use and can be connected to a computer with just one USB cable. The computer can recognize the download function and the two ports corresponding to the JTAG function. 3. ESP-Prog can be connected to the user board using the cable. The connector is available in 2.54mm and 1.27mm pitch packages with a foolproof design. The user board must place the Program (6-Pin) and JTAG (10-Pin) connectors in the corresponding order. 4. Considering that the power supply voltage of different user boards may vary, the two interfaces on ESP-Prog can select a 5V or 3.3V power supply via Pin Header, which has strong power compatibility. Product Description: Size: 73.4mm x 25.1mm Interface: Program; JTAG Steps for Use: 1. Connect the ESP-Prog debug board and the computer's USB port via a USB cable. 2. Install the FT2232HL chip driver on the computer side. The computer recognizes two ports, indicating that the driver has been installed correctly. 3. Use the Pin header to select the power supply voltage of the Program/JTAG interface. 4. Connect the debug board and the ESP product board with the gray cable. 5. Automatic download and JTAG debugging of the ESP32 product board can be achieved using official software tools or scripts.
