Hello,

I have the same fingerprint and said "Did not find fingerprint sensor :("
I don't know what to do!

Best regards

"◆ communication baud rate (UART) : (9600 × N) bps where N = 1 ~ 12 (default value N = 6 , ie 57600 bps ) "

Looks like the Green wire is TX (goes to RX on the Arduino) and the White wire is RX (goes to TX on the Arduino).
