Are you ready to supercharge your XIAO projects? Say hello to our brand new IO Expander, designed to take your connectivity and functionality to the next level.
MCP23017 Power: Powered by MCP23017 from Microchip Technology Inc., this expansion board utilizes the IIC port with blazing-fast 400 kHz communication.
Expand Your IOs: Break out an additional 16 IOs that can output up to 25mA, with configurable input modes.
Extra Connectivity: With 2 power outputs, 1 Grove IIC bus port, and extra output pads (GND, INTB, INTA, RST), you have all the options you need.
But that’s not all! We’ve made it even more versatile:
J1 & J2 Pads: Connect RST, INTB, and INTA pins to D6, D1, and D0 of your XIAO board using J1 pads. Use J2 pads to select the IIC address of the MCP23017 chip.
Grove Compatibility: Grove pads ensure seamless integration with Grove modules, opening up a world of possibilities.
Compact, solderable, and measuring just 21 x 17.5mm, it’s perfect for solder enthusiasts and a game-changer for projects like Wearable Devices, Home Automation, Robotics, IoT Prototyping, and more.
