Led extension board, or output power boards Led extension boards for Arduino, PoKeys, Raspberry... Also, suitable for other microprocessors, read why you need a led extension board. Arduino, Raspberry Pi and other microcontrollers There is also a limit on how much current you can draw through an Arduino board. Typically with Arduino you would be able to use 13 LEDs with 10 to 15 mA per port. These can differ between different types of Arduino or Raspberry boards. In general, it is not a good idea to drive a lot of led’s directly from the controller's output ports. PoKeys cards Pokeys cards can drive LEDs directly through digital output ports. However, doing so is limited to driving the LED with 4 mA and a maximum of 100 mA in total. You will not have much LED light if you only run 4 mA through the LED, except when you buy special LEDs. Normally you need something around 15 to 20 mA to give the LED a normal brightness. This led extension board iis specifically designed for use with Arduino, Pokeys or other Microcontrollers. It can not only drive LEDs, but you can also run any other device that needs more current. Each output can handle about 300 mA per port, and if needed, you can parallel the output ports. This board has 24 outputs and can drive multiple led's per output for a maximum of 300 mA per port. The size of this board = 68 mm x 34 mm Board is completely finished and ready to use, no extra software is needed. Simply connect and use. Power supply is 5 Volt. Resistors are on board.
