The SB200 is designed to be a demonstration platform and an easy-to-use development environment for various AVR based smart battery applications. The SB200 does however introduce more resistance than what would normally be found in a battery pack, which will introduce slight errors when reading the battery cell voltage. Nevertheless, the SB200 is an excellent platform for demonstration, evaluation, and application development for AVR based smart battery application. The following sections describe the main features of the SB200 kit.
