Rev 0.3 of the 48V IBC board came in! Time to start assembling it.
This version has a few bug fixes like "thin trace where there should have been a fat plane" plus a dedicated low noise power rail for the shunt monitors, some lowpass filtering on the shunt outputs to remove the effects of ripple on the current measurements, and moving the 48V shunt out of the high dI/dt path.
