I have spent several hours on the BMS project during this week end and the schematic of the main module is finished now. The PCB patterns of all the components are also drawn :-)

The module implements an NXP LPC1549 Cortex M3 processor running at 72 MHz. This chip is really the perfect choice for this application.

I have chosen the LQFP 48 package. Nearly all the pins are used.

More about this awsome device here.
