Although this thread is old (almost 1 year), I'm trying to find Arduino 101 Eagle board layout and schematic files.
I would like to add a 3.8v li-ion battery to the PV_BATT and VSYS pins and could really use the layout information in any file format, but eagle would be preferred.
Thanks, using the Cadence viewer I've found the vin(1) and vin(2) pads are grounded in a way not easily separated, therefor the on board battery charger isn't available on the Arduino 101. Too bad.
