## Description

The SparkFun Qwiic GPIO adds eight additional digital I/O pins to your project via I2C, based on the TCA9534 I/O Expander from Texas Instruments. Read and write pins just like standard Arduino digital pins using the included library — functions mirror familiar pinMode and digitalWrite calls. All eight pins are broken out to latch terminals for tool-free wire connections. With three configurable address jumpers, you can connect up to eight Qwiic GPIO boards on a single I2C bus for up to 64 additional GPIO pins. Default I2C address is 0x27. Key Features I/O Expander – TCA9534 with 8 digital GPIO pins Interface – I2C via Qwiic connector (1mm 4-pin JST) Default Address – 0x27 (configurable via 3 jumpers, up to 8 boards) Terminals – Latch-style terminals for tool-free wiring Arduino Library – Familiar pinMode/digitalWrite-style functions Ideal For Expanding GPIO on pin-limited microcontrollers Qwiic ecosystem I2C projects Multi-board configurations needing up to 64 extra pins Rapid prototyping with tool-free connections Package Contents 1× SparkFun Qwiic GPIO Board Resources Hookup Guide
