3.8.4 Battery Header J300

The Open-Q 820 / 820Pro µSOM development platform can also power the µSOM with a
single cell Lithium-Ion Polymer (LiPo) battery pack which connects to header J300. The
purpose of this header is to be used by the end user to develop a battery charging solution,
including battery characterization. Intrinsyc recommends using the AA Portable Power
Corp's CU-J479-V2 / 1ICP7/55/85 Lithium ion battery pack. This is a single cell pack with a
nominal voltage of 3.8V and a capacity of 3200mAh (11.8 Wh, 5A rate). If user intends to
use a different battery, please note the pin outs on this battery header.

Please note that the battery only powers the µSOM. To ensure proper functionality of the
development kit, the 12V power supply must be attached at J21. When a battery is not in
use, the TI step down converter U400 is used to power the µSOM.
Note that the software that is shipped with the development kit does NOT support battery
charging. Please visit the Intrinsyc support site and follow the instructions for preparing the
platform to support battery charging.
