Hi all,
I am frustratingly trying to locate a 3.3 v supply to gnd short measuring approx 12 ohms
on my FV1 Dev board - ive eliminated all components connected to 3.3 supply by buzzing or replacing apart from obviously FV1 and CH341 smt chips - there is no visual sign of issues under high magnification
However i was wondering if anyone can comment on the properties of say solder blob
or whisker short ohmic characteristics and debugging and location,
Thx
