Development of the CUMonitor hardware is progressing and the first boards acceptable for consumer release have arrives and are going thru soak testing.
CUMonitor PCB changes
The major changes have been to add the facility to power the board through a micro USB connector adding onboard voltage regulation of the 3.3v. The new A to D circuits can run without the the addition of a burden resistor so these have been removed. This means that the CUMonitor consumer PCB assumes that the 30A 1V current clamps will be used. But this should be OK form most household use cases. The surface mount spaces for the burden resistor have been left in case 100A clamps are required. There was a missing resistor on the previous board that is also fixed.
