The MCP23017 supports up to 8 different I2C addresses so with two MCP23017 devices on each IO Pi you can stack up to 4 IO Pi boards on a single Raspberry Pi giving a maximum of 128 I\/O ports.\u003cbr\u003e\u003cbr\u003eThe IO Pi includes a 5V port that can be isolated from the Raspberry Pi via an isolation solder jumper marked \"Link\" on the PCB so you can use a separate 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 Plus to your Raspberry Pi. The 5V input is compatible with our 5mm screw terminals.\u003c\/p\u003e\n\u003cp\u003eTo use the IO Pi Plus externally from the Raspberry Pi you will need to connect the 3.3V (Pin 1), SDA (Pin 3), SCL (Pin 5) and Ground (Pin 6) pins from the Raspberry Pi GPIO header to the corresponding pins on the IO Pi Plus.  The 5V pin will also need to be connected if you are not using an external 5V power supply.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"467\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"336\"\u003eVdd (5V pin on I2C bus)\u003c\/td\u003e\n\u003ctd width=\"131\"\u003e2.7V - 5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"336\"\u003eAll digital inputs and outputs\u003c\/td\u003e\n\u003ctd\u003e0 - Vdd\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"336\"\u003eCurrent at I\/O Pin (sourced or sunk)\u003c\/td\u003e\n\u003ctd\u003e25 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"336\"\u003eMaximum current on a single I\/O Bank\u003cbr\u003e(1 MCP23017 device)\u003c\/td\u003e\n\u003ctd\u003e125 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eAssembly\u003c\/h2\u003e\n\u003cp\u003eThe IO Pi Plus is supplied with the 40 pin GPIO connector unsoldered. Before using the IO Pi Plus you will need to solder the connector onto the PCB. The power link and I2C address selection are configured using solder jumpers. For your convenience we supply the IO Pi Plus with the power link jumper and one address selection jumper pre-soldered.\u003cbr\u003e\u003cbr\u003eThe digital input pads are spaced 2.54mm apart. You can solder wires directly to the board or use 2.54mm pitch headers. The IO Pi Plus is compatible with 20 pin IDC vertical and right angle headers allowing you to use ribbon cables to connect your external devices to the board.\u003cbr\u003e\u003cbr\u003eTo install the IO Pi simply press the 40 pin connector down onto the Raspberry Pi GPIO pins with the board sat over the top of the Raspberry Pi.\u003cbr\u003e\u003cbr\u003eIf you are installing more than one IO Pi on a single Raspberry Pi board then you will need to configure the address select jumpers for each IO Pi.\u003cbr\u003e\u003cbr\u003eRemove the isolation jumper when connecting an external power supply to the 5V port.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/eQYaIGLPwrA\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\nCode Libraries and Demos\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMCP23017 datasheet\u003c\/li\u003e\n\u003cli\u003eAssembly and I2C address selection\u003c\/li\u003e\n\u003cli\u003e3D CAD Model\u003c\/li\u003e\n\u003cli\u003eSchematic\u003c\/li\u003e\n\u003cli\u003eMechanical Drawing\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABelectronics","offers":[{"title":"Default Title","offer_id":48620803752158,"sku":"iki1787257804304","price":9.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/0705\/9422\/files\/io-pi-plus_1.jpg?v=1787257812","url":"https:\/\/primewearfashion.shop\/products\/io-pi-plus","provider":"My Store","version":"1.0","type":"link"}
