Hello there!
It is possible to have external leds wired from the board? There is pwr/rtk/pps/fence pin outs. Just want to make sure before I start soldering on the board.
Thank you!

Hi Sixthsantos,
The datasheet for the ZED-F9P says “DC current through any digital I/O pin (except supplies): 5mA”. The on-board LEDs will be drawing approx. 1-2mA. You should be OK, so long as your external LEDs draw 1-2mA maximum. I would recommend using a 1k (1000 Ohm) resistor to limit the current.
Best wishes,
Paul
Thank you again Paul!
My leds are 20mA I was playing on using 5k resistors
I found this on the product page https://cdn.sparkfun.com/assets/6/5/7/6 … ematic.pdf
If I go from GND to each led / lesistor to the pin out I should be good to go?
Thank you!
