RasPiO InsPiRing Addressable LEDs for Raspberry Pi - RasPiO Driver only, The RasPiO InsPiRing range are a system of programmable RGB LED boards that can be connected together to make 2D and 3D shapes up to the limits of your imagination. The LED modules are driven by this pHAT-sized driver board for Raspberry Pi. The board has a buffer chip to handle the 5V logic levels and also has space for external power if needed. Pi GPIO ports are broken out and there is space for an optional ADC, which enables control of your LEDs with potentiometers or sensors. For most applications you can take power from the Pi, if your PSU has enough juice. But, if you need to, you can connect an external 5V source and use the alternative connections on the driver board (or add supplementary wires directly to 5V/GND on the LED boards).
