Evaluation Kit for AS1112
AS1112EvalKit
The AS1112 is a 16-channel LED driver with dot correction and greyscale PWM. The evaluation kit is powered via an external power supply and must also be controlled via an external device. This can be done with a SPI-compatible serial interface. Via the output connector different LEDs can be connected to the evaluation kit. More evaluation kits can be connected through the Line in and Line out connectors of each kit.
