{"product_id":"sparkfun-qwiic-gpio","title":"SparkFun Qwiic GPIO","description":"\u003cp\u003eDo you find yourself wishing that you had just a few more GPIO pins? What if you only need that one more pin? You could add another microcontroller to your project but that increases cost and complexity. Instead, you can use the Qwiic GPIO to add eight new pins to your Qwiic project!\u003c\/p\u003e\n\u003cp\u003eThe Sparkfun Qwiic GPIO is an I²C device based around the TCA9534 I\/O Expander IC from Texas Instruments. The board adds an additional eight IO pins which you can read and write just like any other digital pin on your controller. The details of the I²C interface have been taken care of in an Arduino library so you can call functions similar to Arduino's \u003ccode\u003epinMode\u003c\/code\u003e and \u003ccode\u003edigitalWrite\u003c\/code\u003e, allowing you to focus on your creation!\u003c\/p\u003e\n\u003cp\u003eThe TCA9534's pins are broken out to easy-to-use latch terminals; never screw another wire into place! The terminals are relatively roomy themselves, so feel free to latch multiple wires into a ground or power terminal. With three customizable address jumpers, you can have up to eight Qwiic GPIO boards to be connected on a single bus allowing upwards of 64 additional GPIO pins! The default I²C is 0x27 and can be changed by adjusting the jumpers on the back of the board.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe \u003ca href=\"\/en-eu\/collections\/qwiic\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSparkFun Qwiic connect system\u003c\/a\u003e is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-qwiic-gpio-hookup-guide?_ga=2.232035292.2116612807.1602510607-416501732.1599036432\" target=\"_blank\"\u003eGet started with the SparkFun Qwiic GPIO Hookup Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEight Configurable GPIO Pins Available\u003c\/li\u003e\n\u003cli\u003eI2C Address: 0x27 (Default)\u003c\/li\u003e\n\u003cli\u003eHardware address pins allow up to eight boards on a single bus\u003c\/li\u003e\n\u003cli\u003eInput Polarity Inversion Register\u003c\/li\u003e\n\u003cli\u003eControl each I\/O pin individually or all at once\u003c\/li\u003e\n\u003cli\u003eOpen-Drain Active-Low Interrupt Output\u003c\/li\u003e\n\u003cli\u003e2x Qwiic Connectors\u003c\/li\u003e\n\u003cli\u003eDimensions: 2.40in x 1.50in (60.96mm x 38.10mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/2\/e\/4\/6\/c\/SparkFun_Qwiic_GPIO_Schematic.pdf\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/c\/f\/c\/a\/7\/SparkFun_Qwiic_GPIO.zip\" target=\"_blank\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-qwiic-gpio-hookup-guide?_ga=2.232035292.2116612807.1602510607-416501732.1599036432\" target=\"_blank\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/learn_tutorials\/1\/2\/1\/0\/Qwiic_GPIO_Dimensions.png\" target=\"_blank\"\u003eBoard Dimensions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/b\/b\/f\/1\/7\/TCA9534.pdf\" target=\"_blank\"\u003eDatasheet \u003c\/a\u003e(TCA9534)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\" target=\"_blank\"\u003eQwiic Resource Page\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Qwiic_GPIO_Library\" target=\"_blank\"\u003eArduino Library\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/Qwiic_GPIO_Py\" target=\"_blank\"\u003ePython Package\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/Qwiic_GPIO\" target=\"_blank\"\u003eGitHub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":32271528788051,"sku":"DEV-17047","price":5.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/17047-SparkFun_Qwiic_GPIO-01.jpg?v=1602520497","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/sparkfun-qwiic-gpio","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
