Power jumper on OpenScope PCB


Recommended Posts

I've successfully setup, updated the firmware, and calibrated my OpenScope using USB power even though the "Power" jumper for which I've found no information anywhere about is in the received "Prog" position instead of "USB". So, what is that jumper used for and what position should it be in before I close my 3D printed case?

Answer to my own question - the proper position of the jumper is "PROG" as that derives Vcc from the micro-USB connector on the PCB labelled "PROG" whereas the "USB" jumper connection derives or, rather, doesn't derive Vcc from the UNPOPULATED position for a micro-USB connector on the PCB labelled "USB".
