(Prototype Practice Board) USB Cable Disconnection Confirmation Module (A to C)

This is a prototype of an A to C USB cable continuity testing module, designed and implemented by the seller as a hobby.
Like commercial USB cable checkers, it can be used to check if your existing USB cables have breaks or are usable. It is powered by a button battery (CR1632, sold separately).

- Surface-mount components are used, but all are hand-soldered.
- Flux removal is done by wiping with alcohol.
- GND and shield are shorted on the module.
- A 3.9kΩ resistor and a white LED are used, but the seller personally finds it a bit too bright.

This is strictly a prototype and the quality is at a hobbyist level. Please consider this before purchasing (hence the item condition is listed as Used - good).
