#42: The ESPFlash programming header for ESP8266 / ESP32

There are far too many one-off programming headers for Espressif MCUs. I wanted a simple programming header that I could use consistently across my projects, and I was surprised that there hasn’t been any consensus around a single header.

This is my attempt to specify a header format that can be used in future ESP8266 / ESP32 projects, and hopefully could even be adopted by companies that make popular products based on Espressif chips.

  1. Leading the way, good job Jon

  2. I’m not into using the ESP devices other than the Sonoff/Tasmota based on your advice. However it was a very interesting presentation and I hope it does lead to a new standard (or 2).

    I’ve been trying to fin d a standardised pinout. So far I’ve found two – which differ by a single shift – and this is a third way. It may be that it’s better and has good support but I’d like to know that that’s the case.

    1. I showed 9 pinout variations in the video, and also referenced XKCD 927 🙂
