The board is based around the MCP23017 16-bit I\/O expander from Microchip Technology Inc. A MCP23017 expander is included on the board allowing you to connect up to 16 digital inputs or outputs to the Raspberry Pi. The IO Pi Zero Expander is powered through the host Raspberry Pi using the GPIO port and extended pins on the GPIO connector allow you to stack the IO Pi Zero along with other expansion boards.\u003c\/p\u003e\n\u003cp\u003eThe I2C address bits are selectable using the on-board jumpers. The MCP23017 supports up to 8 different I2C addresses so with one MCP23017 device on each IO Pi Zero you can stack up to 8 IO Pi Zero boards on a single Raspberry Pi giving a maximum of 128 I\/O ports.\u003c\/p\u003e\n\u003cp\u003eThe IO Pi includes a 5V port that can be isolated from the Raspberry Pi via an isolation solder jumper so you can use a seperate high current power supply to power the IO Pi reducing the load on the Raspberry Pi. Use of an external supply is recommended if you plan on connecting more than one IO Pi to your Raspberry Pi.\u003c\/p\u003e\n\u003ch2\u003eI2C Address Selection\u003c\/h2\u003e\n\u003cp\u003eThe MCP23017 contains three address select pins which can be tied to Vss or Vdd. This gives 8 possible I2C addresses for each chip. The IO Pi Zero contains one MCP23017 chip so you can stack up to 8 IO Pi boards on a single Raspberry Pi. To simplify address selection on the IO Pi we have included a set of address selection pads which can be configured by applying a small solder bridge across the required pads. The table below show the recommended configurations for your IO Pi and the associated I2C addresses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cbr\u003eDisconnect the IO Pi from the Raspberry Pi before changing the address pins. The address pins are tied to GND (low) via a 10K resistor so the jumper is used to tie a pin to Vcc (high).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDefault Configuration (IC1 =
