Schematic drawing software for Arduino, Raspberry Pi, and other Single Board Computers (SBCs) is essential to developing electronics projects. When it comes to creating circuits on a SBC, it’s ...

There are a number of pins that have incorrect GPIO designation in the pinout drawing, compared to the actual board (and schematics). Examples are Rx and Tx pins which should be GPIO38 & 39, the ...

In the Arduino schematic, for some reason pin 2 on the NINA-W102 is labeled "GPIO34". At first I thought I was mistaken, and that pin 2 on the Arduino schematic really is GPIO34 on the NINA, but that ...
