The EVBMA7318-SPI provides a solution for a distributed architecture for lithium-ion battery management in automotive and industrial applications. This board integrates one BMA7318 device. It can communicate with a host board or host PC via SPI and with other CMU boards via TPL using transformer isolation. Each board can measure lithium-ion batteries with 4 to 18 cells. The board is powered by a 9 VDC to 90 VDC power source.
