Overview

The Digilent PmodLED contains 4 individual user LEDs that are driven through logic-level transistors.

1 Functional Description

The PmodLED 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.

2 Interfacing with the Pmod

The PmodLED 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.

The PmodLED.

 4 high-bright LEDs

 Required driving current of less than 1 mA

 Easy-to-see logic level indicators

Features include:
