This IO expansion board interfaces with the CarPiHAT via its i2C header and provides an additional 8 GPIO pins, 4x 1A outputs and 4x opto-isolated inputs.
Screw terminals allow easy wire-to-board connections and Molex nano-fit headers have been used for a secure connection to a CarPiHAT in an automotive environment.
The board is designed to be mounted on top of a CarPiHAT using appropriate screws and spacers (included).
Note: You need a CarPiHAT to use this board. A CarPiHAT is not included! Grab the original CarPiHAT here, or the PRO version (with onboard DAC) here.
Features
12-24V fused input voltage
Molex Nano-fit connectors for I2C channels
4x Opto-Isolated inputs
4x 1A VCC switched power outputs
8x GPIO outputs
GND and 3.3V rails
I2C Address selection jumper pads (0x20-27)
Example Use
An automotive scenario where the CarPiHAT’s two inputs and outputs and not sufficient. This could be power to devices or lighting circuits for instance. The GPIO header can be used in the same fashion as a Pi’s. Refer to the documentation for implantation libraries and examples.
