Here's a nice, not too short interview with Ander:

MMMMMMMOOOOOOOOAAAAAAAAAAAAAAARRRRRRRRRRRRR!!! :frantics:

Well spotted ;) Your are right, the PCB is the same for all modules. It can hold either one encoder or two pushbuttons in the same area, or any kind of sensor with analog output. One PCB can hold 16 pushbuttons or 8 encoders/sensors, or any combination. Actually, one module consists of all the necessary PCB stuff for - one STM32 core - 2 DINs (in a SMD version) - one step down converter (24V to 5V) - three driver chips to drive 16 RGB LEDs (PCA9635). This is a design of my own, I do not use DOUT modules The core parts are of course not soldered in on every module, but of course this one PCB design made developing and producing the PCB much cheaper. Its actually 4 Layers, 16 RGB LEDs need quite a lot of routing...

Thanks Wilba for posting the pictures. BTW, this was all hand-soldered by me.... Very meditative. I have made a quick drawing of the button mechanism. It works quite well, you can push on it everywhere on the surface and it activates the button. I selected a pushbutton with only 150g of force.

While I am at it: Many thanks to you for supporting me during this project. I could not have done it without the help of you and the great MBHP. I will try to post some photos, source and docs here in due course.
