Yay! Another remix!
This is a small adaptation of the (pigrrl2-bot-v1-2) PiGrrl 2 that gives you an easy place to put some 3mm LEDs for charging status, since you can't see / can barely see them from inside the PiGrrl.
Since the Powerboost 1000c only has a breakout pin for the low battery LED, I removed the SMD LEDs from the board and wired up my own LEDs. One wire from the 5V side of the SMD LED, to the positive side of all 3 LEDs, then a 330 ohm resistor after each LED. The green and yellow go to their respective pads on the board (where the SMD LEDs were mounted) and the red goes to the LBO pin.
The LEDs kinda "snapped" in on mine, but I secured them with a small drop of superglue when I had everything wired up.
