I have a fingerprint with flat cable (20 pin), how could I know the digram of this cable.
Thanks
RTFM, to get the needed information ?
Anyone can help which pins are the TX and RX in the above diagram ??
I can´t dedect any pin with this name.
Perhaps there is a different type control chip on the back of the photo.
In other words, it is different as a module from the 20-pin flat cable type linked to in post #1.
Maybe the post #1 model can't communicate via Tx / Rx.
