Just a reminder about what rails and signals are where on the rear of the 'Slothie' issue VI MK14 PCB, and therefore also on the rear studs of the edge connector on RealView, looking at the studs from the rear of the PCB.

The essential connections are 0V, Sense-B and SIN. +5V is not actually necessary as long as the module has plenty of battery charge to run on but if you do take +5V from the MK14 to the module then IMO it needs to go the the '5V In' pin on the 8-way connector on the M5StickCPlus module, not to the 5V connection on the 4-way Grove connector which is an output, not an input.
