1 Introduction
The ATAVRSB201-1/SB201-2 kits are evaluation and development kits for the new
Atmel AVR
packs with 1 series or 2 series lithium ion and lithium polymer cells, and feature
autonomous battery protection as well as very accurate voltage, current and
temperature monitoring capabilities. The device provides the means to protect the
battery pack and surroundings from hazardous conditions and gain the most from
the batteries.
The kits consist of both hardware and firmware, with hardware documented here
and firmware in application note AVR456. The boards have an edge connector for
connection to ATAVRSB200 Smart battery Evaluation kit, but can for development
purposes also be used alone.
