High Voltage Arduino Pins

Maybe you have also looked at some Arduino circuits posted online and noticed an interesting way in how some circuits handle high input pin voltages. With high I mean anything above the typical Vcc + 0.5 rating given in the ATMega328p datasheet. Lets look at an example, in a previous post I discussed building a […]

Getting started with STM32F1

If you are like me, you often find yourself opening some electronic device to see what makes it tick and maybe discover some new magic part. Recently this was the case with some new parts that I bought for my FPV drone and could not help noticing how many of these devices used STM micro-controllers. […]
