I received a Adafruit PowerBoost 500 Shield - Rechargeable 5V Power today, soldered in the headers and switch, attached a LiPo 3.7V 2000mAH battery and set it in my adafruit Metro. Initially, it worked fine: flip the switch, lights on both boards turn on, brilliant.
Then I plugged in the system it was running: a data input at pin 5 from an LED strip, and then outputs from 5V and GND that split to give power and ground to that LED strip, and then continued on to a second adafruit Metro (VIN and GND) to power that board and the separate LED strip it controls (I use two boards for various reasons, can explain more fully if useful). And I flipped the switch! And for two great seconds, all the LEDs worked with both different animations! And then they stopped.
And now the poor thing won't do anything at all. I flip the switch, no lights. The orange CHG light on the shield and the green ON light on the Metro turn on when I plug them into a miniUSB from the wall, but nothing else. I've also tried with another identical, fully charged battery. Nothing.
Is it possible I've drawn too much and blown a fuse? Have I set up something wrong? Even if I can fix or replace this shield, would it be preferable to power the bother Metro with a separate battery and shield? All input gratefully received!
