ESP Development Test Programmer Adapter ESP-01/ESP-07/ESP-12/ESP32

This versatile ESP development board and test programmer adapter provides a convenient solution for programming, testing, and prototyping with various ESP8266 and ESP32 modules. Designed to accommodate multiple ESP module footprints including ESP-01, ESP-07, ESP-12E/F, and ESP32 boards, this adapter eliminates the need for multiple programmer boards. The integrated USB-to-serial converter enables direct programming from Arduino IDE or other development environments without external adapters.

Featuring onboard voltage regulation, auto-reset circuitry, and clearly labeled GPIO breakout pins, this board simplifies ESP module development and debugging. The breadboard-compatible pin headers allow easy prototyping and circuit testing. Includes multiple power supply options (USB or external) and status LEDs for power and serial communication indication. Perfect for IoT development, WiFi projects, and embedded system prototyping. The compact design with DIP switches for boot mode selection streamlines the flashing process. Ideal for beginners learning ESP programming and professionals requiring a reliable development platform for ESP-based projects.
