CBC3105-R4C Evaluation Board
The CBC3105-R4C evaluation board as shown in the photo and schematic below is included in the CBC-EVAL-
05B EnerChip CC Evaluation Kit. This board is 16 pins in the same 24-pin DIP configuration as the EVAL-
05 CBC3150/CBC3112 eval board. This eval board is easy to use with proto-boards or sockets for design
evaluation.
Note that the Enerchip CBC3105 is shipped in a charged state and it is advised to not solder the CBC3105
evaluation board to another board as the high temperatures of a manual soldering process are outside the
CBC3105 operating specifications.
