The SparkFun Qwiic adds 8 more I/O lines that are I2C addressable. And they are chainable for even more I/O lines!In stock + SparkFun Qwiic GPIO Board quantity $5.79 USD- Add to cart SKU: 50685 Categories: Adapters, Connectors, I2C/TWI, Parts, Wired Tag: allAccounts Description More Info Reviews (0) Description Microcontrollers are getting smaller and cheaper, but sometimes a bit too limiting when you ‘ve found you’ve run out of digital I/O lines. SparkFun’s solution is this: the Qwiic GPIO expander that uses the the I²C communications standard via the TCA9534 I/O Expander IC to add 8 channels to your project. 8 channels not enough? Daisy-chain up to 8 units for 64 additional channels of data! Fortunately, SparkFun has made it easy to use in an Arduino library so you can call functions similar to Arduino’s pinMode and digitalWrite, so no “creative coding” is required. The 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. Features Eight Configurable GPIO Pins Available I2C Address: 0x27 (Default) Hardware address pins allow up to eight boards on a single bus Input Polarity Inversion Register Control each I/O pin individually or all at once Open-Drain Active-Low Interrupt Output 2x Qwiic Connectors Dimensions: 2.40in x 1.50in (60.96mm x 38.10mm) Documentation Hookup Guide More Info Weight 0.025 kg Dimensions 7 × 5 × 2 cm Ecosystem Raspberry Pi Reviews There are no reviews yet.Only logged in customers who have purchased this product may leave a review.
