**This is for version 1.0-a/b/c.** Version 1.1 has dedicated pins.
# 1.1-a
# Power
The power `PWR` and activity `ACT`pins are on the board behind the SD Card. You can install `1/8w` resistors at `R1`/`R2` on the top edge of the PCB. Kits and Assembled units come with `330`ohm, but anything between `300`-`500` should be safe. Your LED will be dimmer the higher the resistance. You can use the calculator at the bottom to calculate the exact resistance you need if you know the LED value.
# 1.0-a/b/c
## Power
Connect a LED to 5v with a resistor rated for your LED.
# Activity
## Activity
There are a few options, but none would be considered easy.
