Layout finished

Due to production costs we decided to go a step further and integrate the functions of the Battery-Management-System – Master (short BMS master) also onto the X-by-Wire board. When the boards are ready we are going to assemble the PCB in two ways.

If its assembled in the first configuration with only one CAN Module and SPI Drivers, its the board with X-by-Wire function. The second configuration is with two CAN Modules, a RS232 Interface and no SPI Drivers, then it has to be the BMS  master Board, wich monitors during charging our 400V cell stack, the voltage of every cell.

First steps – SMT

One of my first full SMT Layouts was a analog to digital respectively digital to analog multi I/O card with a lot of op amp stages and a SPI digital to analog converter.

The main usage for these electronics was in industrial automatic test equipment. Several of this cards were connected in a stack to measure 80 Voltages and 20 Temperatures.
