Compact USB-C-to-UART programmer for the ESP8266/ESP32 series. Automatic reset & boot — flash with esptool, Arduino IDE or ESP-IDF
The HardCode HC22002 is a compact USB-C-to-UART programmer for the ESP8266/ESP32 series. It handles the automatic reset and download-mode entry for you, so esptool, the Arduino IDE and ESP-IDF flash firmware with no manual button sequence — no "boot-button dance."
Because it's USB bus-powered, one cable carries both power and data — no wall adapter needed. On-board RST and BOOT buttons are there for manual control whenever you want it.
Ideal for bringing up custom ESP boards that don't carry their own USB-serial bridge, small-batch firmware loading, and serial debugging on the bench.
Features
- USB-C, bus-powered (power + data over one cable)
- Automatic reset / auto-boot — flash with zero button presses
- On-board RST and BOOT buttons for manual control
