From the project
KiCAD source files for Manuvr's motion capture glove.
This is a backplane PCB for Digitabulum containing the power-management block and associated support circuits.
This PCB, combined with a Compute board, and a Digitabulum-r2 board (plus sensors) forms a complete electronics package for a single motion-capture glove.
The power-management block of this backplane is broken out in the PowerPlant-Module.
The CPLD GPIO pin has been routed to the 2v5/3v3 selection signal.
