8558-BCS-A4a PCB

The BCS-A4a (Battery-Charger-Solar, with ALF4all sandwich interface) boards (10068 and 8558) are prototyping boards designed as power provision and sensor support platforms for a range of processor modules that are connected through the 2 x 7 pin ALF4all 'Sandwich' interface, which breaks out SPI, I²C and serial Tx/Rx pins, as well as four (A0 – A3) control pins.

ALF4all Sandwich Interface Configuration

The 8558-BCS-A4a board is a cut-down version of the 10068-BCS-A4a board, designed to fit within the smaller 85 x 58 enclosure.

Board Layout

The various subsystems are identified in the board schematic and laid out as illustrated below:
