Here’s a brief historical and technical overview to help us understand what a bootloader is, why you need it, and what it has to do with Marlin and STM32. Arduino boards use a special bootloader that ...

The Arduino Uno Q is an exciting device, essentially consisting of two distinct computing environments living on the same PCB. Its dual-processor design provides the power of a quad-core ARM A55, for ...

This time I will present you a classic 7 segment display alarm clock which will represent another one from my series of DIY unusual and ordinary clocks which you can watch on my playlist. In this case ...

I have a bit of a love/hate relationship with the Arduino. But if I had two serious gripes about the original offering it was the 8-bit CPU and the lack of proper debugging support. Now there’s plenty ...

This is a fully custom made STM32-based PCB (Printed Circuit Board). Being completely custom, it has an advantage over commercial DevKits in that you can customize its shape and application. (In ...
