The power supply board for EOS2 is now pretty much finished. This is the first PCB in the EOS2-project, and probably also the biggest. This means the dimensions of this PCB will define a standard to use for all future PCBs, so these can be easily stacked. The standard also includes an 8x2-pin header, so the stacked PCBs can be supplied with power and communicate through an I2C-bus.
The design is a hybrid of switch mode and linear regulators, and voltage and current can be read out through the I2C-interface in the header. You can read more about the design in the Wiki:
