README

Wii Sensor

A 2xAA Battery or USB-C powered IR sensor bar compatible with the Nintendo Wii and Wii-U. The PCB can be broken off at the perforation and then the width of the bar extended by soldering wires onto the test points; this allows for better performance on larger TVs. The constant current drivers for the IR LEDs have potentiometers that can adjust the LED brightness, lower for extended battery operation or higher for bright sunlit rooms. The power switch toggles from battery power to USB-C power. A red LED will light up when on battery power.
