Description

The ESP Programmer (V2) is the successor of ESP8266 Programmer, a board to upload firmware on ESP8266, ESP32, and ESP32-S2. Like the predecessor, it benefits the USB-C connector, but it is improved replacing the CH340 with Silicon Labs CP2104 USB-serial converter (smaller footprint), adding 2 LEDs to show the status of RX and TX line and improving ESD protection.

It can be attached to your target board through 2 connectors:

  • "standard" Lolin D1 mini shield form factor. If you are not going to use this form factor, you can break the external frame gaining some mm^2 (video).
  • 1x06 1.27mm-pitched header. This miniaturized pitch was chosen to save as much area as possible. For the traditional 2.54mm pitch, please consider the previous version of ESP8266 Programmer.
