- 4 high-bright red LEDs
- Clearly visible logic level indicators
- Required driving current of < 1 mA
- 6-pin Pmod connector with GPIO interface
The Pmod LED utilizes logic-level transistors to light up four individual high-bright LEDs. Each LED can be turned on through the use of less than 1 mA of current, making this Pmod ideal for users needing small indicator lights.
Interfacing with the Pmod
The Pmod LED communicates with the host board via the GPIO protocol. A logic high level turns on the LED and a logic low signal turns off the LED .

It is recommended that the Pmod LED is operated at 3.3V.
The pins on the pin header are spaced 100 mil apart. The PCB is 0.8 inches long on the sides parallel to the pins on the pin header and 0.8 inches long on the sides perpendicular to the pin header.
