## Description

The Raspberry PI HAT - 32 I/O Ports Expander (HAT32IOPEBK) 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. This is a kit edition, in order to solder it, you only need a soldering iron and tin.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 HAT32IOPEBK 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 HAT32IOPEBK 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 HAT32IOPEBK 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 HAT32IOPEBK keeping it open. In order to power the HAT32IOPEBK 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 HAT32IOPEBK boards to your Raspberry Pi. Specifications: -Vdd (5V polarized input header without BACK PWR): 4.5V - 5.5V -All digital inputs and outputs: 0 - Vdd -Maximum current on a single I/O Pin (sourced or sunk): 25 mA -Maximum current on each MCP23017 chip: 125 mA

## Features

- 32 Digital Inputs/Outputs, based on the Microchip MCP23017 chip     Control via the Raspberry Pi I2C port, selectable I2C addresses thru switches     Stackable, up to 4 boards per Raspberry Pi, right angled headers for ease connection when stacked     All I/Os are 5V tolerant, built in 3.3V to 5V shifter for Raspberry Pi I2C port protection     Raspberry Pi can be Back Powered or isolated thru a jumper, The board can be powered thru the Raspberry Pi GPIO 5V pins, or thru a 5V polarized input header from an external supply

    Worth it.
  

*by D***E on Reviewed in the United States on April 30, 2017*

Fun to build, but had to look on line for parts placement.  Would have liked a layout included.  Still easy to assemble.
