Ordering finished PCBs is becoming easier. Nevertheless it can happen that you don't want to order PCBs or you just don't want to solder the SMD LEDs.

That's why I created a template in which you can insert finished LEDs and solder them together. So you can avoid having to solder SMD components. Nevertheless, soldering the 24 individual LED boards is quite a fiddly job.

In addition, of course, no ESP32 can be installed on the template. That means you have to control the LEDs from an external microcontroller. This can be installed in a base. I will post information about this soon. :)
