HowTo: pxlBlck - flashing firmware with the esp web tools directly from the browser

Flashing the ESP8266 or ESP32 is not so easy if you have not had much contact with microcontrollers before.

However, there is now something very cool that makes this process super easy. The people behind ESPhome have a web flasher which allows you to flash ESP microcontrollers directly from a Google Chrome browser. Without installation and configuration effort. What's even cooler is that they are making the tool available for free so that others can use it too.

You can now use the pxlBlck firmware without great effort directly from the Google Chrome Browser flash.

For those who want to get started right away: Click on the button below and give it a try!

This works only in Google Chrome! Please make sure that you access this page via HTTPS!

For those of you who want more details, I have included the Flash firmware step by step prepared illustrated instructions.


So that you can program your pxlBlck, you should of course have already prepared the hardware accordingly. There are several ways to do this. You will find a few examples in the following section. A complete list of all possible platforms can be found under the following keyword

I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are always welcome. 🙂

PS Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you think it's cool that I share the information with you, I would be happy about a small donation to the coffee fund. 🙂
