5.3 Revision 5

Revision 5 is the initially released revision.

GM02S delivered with modem firmware version: LR8.0.5.10-55042-cs0.

Some boards are delivered with pin-headers with too many positions to fit in the through-hole connectors on the board edge. Remove these extra pins before mounting to the board.

Known issue:

The battery charger is configured for a 500 mA charge current, and the board may use more current than the USB 2.0 specification allows.

The 32.768 kHz crystal load capacitors are not tuned optimally. Replace C106 with a 6.8 pF capacitor for better frequency accuracy.
