ESP8266 & ESP32 Programmer Board

The CH340C USB Type-C ESP8266 & ESP32 Programmer Board is a reliable USB-to-UART programming adapter for ESP8266 and ESP32 development. Whether you're uploading firmware, debugging applications, monitoring serial output, or developing IoT projects, this programmer offers stable and dependable performance.

Equipped with the CH340C USB-to-Serial converter, the board delivers fast UART communication while benefiting from the chip's built-in clock, eliminating the need for an external crystal oscillator. The USB Type-C connector ensures convenient connectivity with modern computers.

This programmer supports both manual and automatic programming on compatible development boards. Boards that expose the required DTR/RTS, EN, and BOOT connections can be programmed automatically, while custom boards may require manual BOOT and RESET operation.

Compatible with popular development environments such as Arduino IDE, PlatformIO, and ESP-IDF, this programmer is an essential tool for makers, students, engineers, and embedded developers.
