Check out my 3DP Tech You Tube channel. This repository contains support files for the "Build a 3D Printer Control Board" series. In this video series I explore the electronics of a 3D printer. I ...

So, I've made a custom board with a standalone atmega328p, running with an Arduino bootloader (it might not be the best option, but that's how I know to run it). And essentially everything is working ...

Each connection to the Arduino I/O drives an LED anode, while the cathodes are joined between the diodes of each plane and go to lines A, B, C, and D, which will be cycled to logic low. So, as far as ...

Traditional Arduino boards assign digital pins in a specific order, but the UART interface on the RP2350 has a different configuration. Adafruit has implemented a small switch that allows users to ...

Documentation is limited with PDF schematics, “board shape”, 3D STEP file, blink code samples for the Arduino IDE and VS Code (C program), as well as a datasheet and user manual for the RA4M1. But it ...
