The 16-Port I/O Expander Module is designed for easy expansion of I/O ports using the I2C bus. With just two wires, it allows the expansion of 16 I/O ports. The module supports driving 16-channel common anode constant current LEDs with 256-step linear dimming and controllable current. It generates an output interrupt (INT) signal when there is a change in the state of an input port. The I2C address can be configured by shorting the A0/A1 jumpers. The module provides two connector options: PH2.0 header and/or solder pads, enabling the stacking of multiple I2C modules. It features an onboard voltage translator that is compatible with 3.3V/5V level systems. The module comes with development resources and a manual, including examples for Raspberry Pi, micro:bit, Arduino, and STM32.
