* available voltage, current and output power depend on capabilities provided by your power source
* higher outputs require lower guage wires (thicker) and adequate ventilation to ensure the board is kept cool.
Configure
The board has a light sensor which reads your desired configuration from the light pulses generated on this page. You can therefore configure your board from any device with a screen and a Javascript capable browser (e.g. Smart phone/watch, laptop). Watch the how-to video or jump right into it below.
