The pHAT features \u003cstrong\u003ea single removable MCP23017 DIP IC\u003c\/strong\u003e, which utilise two i2c pins (which can be shared with other devices if required), and in exchange gives your Raspberry Pi Zero an additional 16 GPIO ports! Each I\/O pin can be configured as an input, output or an input with a pullup resistor. The MCP23017 pHAT is stackable, featuring selectable i2c address jumpers which supports up to 8 independent addresses: This means you can add up to 128 additional I\/O's to a single Raspberry Pi by stacking up to 8 MCP23017 pHAT's! \u003c\/p\u003e\n\n\u003cp\u003eThe MCP23017 pHAT can also be used to protect your Raspberry Pi! We've used removable, rather than surface mount, \u003cstrong\u003eMCP23017 DIP IC's\u003c\/strong\u003e which can act as replaceable buffer for the Raspberry Pi's GPIO, essentially protecting your Raspberry Pi from damage via the GPIO ports. The MCP23017 pHAT is powered via the Raspberry Pi's GPIO port, but features an included (but unsoldered) terminal block for advanced users wanting to use an external 5V source, or stack multiple MCP23017 pHATs on a single Pi. \u003cstrong\u003eThe isolation jumper \"PWR JUMPER\" must be removed when using an external source.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe product comes fully assembled with our push-fit \"plug \u0026amp; play\" Single Shroud Header, Socket Header, and 14mm HAT Mounting Kit\u003cstrong\u003e,\u003c\/strong\u003e so there's no soldering required, and you can get started in no time with our Wiki \u0026amp; Example Code! \u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003ePlease Note.
