This kit includes a 5-inch by 5-inch circuit board with an AAT003 Angle Sensor, 60 multicolor smart LEDs (6° spacing) to indicate rotation angle, and a preprogrammed, onboard ATtiny microcontroller.
The microcontroller also provides a PWM angle output. The board is factory calibrated and can optionally be field calibration.
A split-pole magnet, a magnet locating fixture, and a 5-volt wall mount power supply module are also included.
The board comes preprogrammed, but the Arduino compatible software is available on Github/NveCorporation so you can use the routines in your own application.
