This US$35 board is intended to stimulate the teaching of basic computer science in schools. Connection of a GPIO to a voltage higher than 3.3V will likely destroy the GPIO block within the SoC. Raspberry Pi single-board computers have their own set of GPIO headers, but this article is going to focus on the 40-pin connector of the newer models: Raspberry Pi 3 and Raspberry Pi Zero/Zero W. Let’s start by looking at the figure on the left. The GPIO header on your Raspberry Pi has a total of 40 GPIO pins. The choice of GPIO 17 was simply because I considered it less likely to conflict with other peripherals likely to be in use. The only conclusion I can come up with is that the Raspberry Pi GPIO inputs are 5 Volt safe, and that there is some kind of protection which kicks in around 5.8 Volts. The power requirements of the Raspberry Pi increase as you make use of the various interfaces on the Raspberry Pi. Note: Pins on the PiFace are 200 through 207 for both reading and writing, with pins 208 through 215 reading the state of the output latch register (ie. Connect the Arduino to the Raspberry Pi.
