Espressif ESP-Prog-2 Development & Debugging Tool for ESP32/ESP8266
The Espressif Systems ESP-Prog-2 is a professional development and debugging tool designed for ESP32 and ESP8266 series microcontrollers. It supports automatic firmware downloading, serial communication, drag-and-drop programming, and JTAG online debugging, making it ideal for developers working on embedded IoT projects and custom ESP-based hardware.
Built around the ESP32-S3-MINI-1 module, the ESP-Prog-2 provides reliable debugging and programming support for ESP8266, ESP32, ESP32-S2, ESP32-S3, and ESP32-C3 devices. It connects to a computer using a single USB Type-C cable and automatically creates separate ports for firmware flashing and JTAG debugging. The board supports selectable 3.3V or 5V target power output through jumper settings, ensuring compatibility with different development boards and embedded systems.
Key features include dual debugging interfaces, onboard USB connectivity, automatic reset/download circuitry, JTAG debugging support, serial communication, and extended GPIO connectors with both 2.54mm and 1.27mm pin headers. The RX/TX and JTAG signal levels operate at 3.3V logic for safe communication with ESP devices. Its compact and easy-to-use design makes it suitable for firmware development, debugging, prototyping, and production testing applications.
