You may have noticed that the MCU on Raspberry Pi is much more complicated than the one on Arduinos. It is usually BGA encapsulated, and stacked with one DDR memory. That means short circuiting the GPIO can be fatal - burning the CPU on Raspberry Pi, and unlike the arduino UNO, there is no comeback.So we made this GPIO Extension Board for Raspberries Pi, with protection design. Normally there is no level conversion on extension boards, which means inadequate load capacity which may lead to...
