Servo S3003 - condition unknown
Labeled as S3003, but probably counterfeit. No guarantee it will work - read description!
(edit with the Customer Reassurance module)
Servos bought with inventory of closing shop with DIY stuff. Hence I don't know source and what are (declared) parameters. Tested with simple sketch (Arduino UNO, Servo library, example sweep) powered with external power supply - don't work reliable. Sweep is not 180°, some of them stalls (with current draw 1.3A@5V) but forced to move by hand start working. Or not.
Condition of modules is unknown, maybe they are broken.
In case You have more experience with servos pictures of internals will tell you more. Instead of throwing them to the electro waste maybe somebody find them useful.
