This is a simple board designed to create a variety of lighting effects based on LEDs. On the board are eight groups of three LEDs in each group. Each group is independently controlled by microcontroller outputs. LEDs are powered by 20 milliamp linear drivers NSI45020. If necessary, drivers with a different current can be used. There is an ISP programmer connector on the board. Inactive microcontroller pins can be used to extend functionality.
The microcontroller runs on an internal oscillator whose frequency is set during programming.
The size of the board is 50х50 millimeters.
