Designed for Raspberry Pi models A+, B+, 2B, and 3B, it supports up to 4 stacked boards for a total of 128 I/O ports. With selectable I2C addresses, 5V tolerant inputs/outputs, and flexible power options including back-power isolation, this HAT is engineered for scalable, safe, and versatile Raspberry Pi projects. ## Description The Raspberry PI HAT - 32 I/O Ports Expander (HAT32IOPE) board is a 32 Input/Output digital expansion board designed for use on the Raspberry Pi A+, Raspberry Pi B+, Raspberry Pi 2 Model B, and Raspberry Pi 3 Model B. The board use two Microchip MCP23017 16-bit I/O expander, allowing you to connect up to 32 digital inputs or outputs to the Raspberry Pi. The HAT32IOPE is connected to Raspberry Pi using a 20x2 GPIO connector with extended pins that allow you to stack many extension boards in a single Raspberry Pi. You can select the I2C address using the on-board 3bits switches (ON=0 the pin is grounded, OFF=1 the pin is pull up to 5V). The MCP23017 supports up to 8 different I2C: Due to there are two MCP23017 per board you are allowed to stack up to four HAT32IOPE boards on a single Raspberry Pi for a maximum of 128 I/O ports. The right angle headers allow you to connect the I/Os while the boards are stacked. The HAT32IOPE may be powered thru a 5V input polarized male connector (now on a right angle connector, female cable to connect external supply included) or thru the Raspberry Pi GPIO 5V pins. If you use the first option you can power the Raspberry Pi shorting the "Back PWR" jumper or isolate the Pi and HAT32IOPE keeping it open. In order to power the HAT32IOPE thru the Raspberry Pi GPIO 5V pins the "Back PWR" jumper must be shorted. Use of an external supply is recommended when you connect more than one HAT32IOPE boards to your Raspberry Pi.
