You need an MCP23017 port expander chip!\u003c\/p\u003e\n\u003cp\u003eIt uses two i2c pins (which can be shared with other devices if required) and in exchange gives your microcontroller another 16 GPIO's! Each I\/O pin can be configured as an in input, output or input with a pullup.\u003c\/p\u003e\n\u003cp\u003eThe chip can also be configured for interrupts for when an input changes, so you don't need to keep polling the chip!\u003c\/p\u003e\n\u003cp\u003eThis one comes in a DIP package, so it's great for breadboarding! You can also set the i2c address for up to 8 unique chips on the same i2c bus, which means you can daisy-chain these IC's to give you up to 128 I\/O's!\u003c\/p\u003e\n\u003cp\u003eDon't forget to grab a matching IC DIP socket for your project!\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e16 bit remote bidirectional I\/O port\u003c\/li\u003e\n\u003cli\u003eHigh-speed I2C interface\u003c\/li\u003e\n\u003cli\u003eThree hardware address pins to allow up to eight devices on the bus\u003c\/li\u003e\n\u003cli\u003eConfigurable interrupt output pins\u003c\/li\u003e\n\u003cli\u003eINTA and INTB can be configured to operate independently or together\u003c\/li\u003e\n\u003cli\u003eConfigurable interrupt source\u003c\/li\u003e\n\u003cli\u003ePolarity Inversion register to configure the polarity of the input port data\u003c\/li\u003e\n\u003cli\u003eExternal Reset input\u003c\/li\u003e\n\u003cli\u003eLow standby current: 1?A max.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAutomation \u0026amp; Process Control\u003c\/li\u003e\n\u003cli\u003eAutomotive\u003c\/li\u003e\n\u003cli\u003eClock \u0026amp; Timing\u003c\/li\u003e\n\u003cli\u003eConsumer Electronics\u003c\/li\u003e\n\u003cli\u003eDefence, Military \u0026amp; Aerospace\u003c\/li\u003e\n\u003cli\u003eEmbedded Design \u0026amp; Development\u003c\/li\u003e\n\u003cli\u003eLED Lighting\u003c\/li\u003e\n\u003cli\u003eIndustrial\u003c\/li\u003e\n\u003cli\u003eMotor Drive \u0026amp; Control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBus Frequency\u003c\/strong\u003e: 1.7MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Configuration\u003c\/strong\u003e: 16bit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIC Interface Type\u003c\/strong\u003e: I2C, Serial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterface Case Style\u003c\/strong\u003e: DIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo. of I\/O's\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo. of Pins\u003c\/strong\u003e: 28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Voltage Max\u003c\/strong\u003e: 5.5V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Voltage Min\u003c\/strong\u003e: 1.8V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eDatasheet\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eAdafruit Adruino Library\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eRaspberry Pi MCP23017 Tutorial\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":53751178625387,"sku":"thv1787257940498","price":1.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/1268\/3883\/files\/mcp23017-port-expander_1.jpg?v=1787257949","url":"https:\/\/pickvirello.com\/products\/mcp23017-port-expander","provider":"Pickvirello","version":"1.0","type":"link"}
