Most microcontrollers and single board computers (SBCs) like the Raspberry Pi have digital outputs that can only supply a current of a few milliamps. This means that you can only use them with low-power LEDs, but if you want to control a high-power LED light bulb then you need to use the microcontroller or SBC's output pin to switch the LED light bulb on and off (using a transistor).
The illuminata includes a transistor to switch its three high-brightness LEDs on and off. This is why the Illuminata has three pins. Two are for power and the third is the control pin that switches the lamp on and off.
Below you will find an example of how the board works
- 3V to 6V operation.
- Built-in MOSFET for PWM and on/off control
- Pre-soldered pin headers (GND, Control and +V)
- Breadboard friendly
- Laser-cut diffuser (superglue required)
- Cool Aluminum PCB
- M2.5 mounting holes
- 1x Illuminata board (pre-soldered)
- 1x Diffuser (superglue required!)
