Fingerprint sensor not working..
Just got hands on my brand new fingerprint sensor. Wired up to my arduino as shown in the example (not that difficult :) ) the sensor doesn't power up.
The red backlight came up for a flash, then USB stopped working due overload.
OK, powersupply with current limiter set to 150mA, also over current. 200mA, still the same :cry:
So whats next? - Got a broken part?
