TIDA-00288: Additional LEDs on each port

Art Mecina

Part Number: TIDA-00288

Hello Guys,

Good day.

Our customer wanted to know if adding four LEDs to TIDA-00288 will have no effect on the normal operation of the design?

The LEDs will be added on the output port. They draw 40mA and 0.4mW each. They just trying to make sure that if the port goes down they can monitor it.

Thanks to confirm!
