Hello, I am new to RFID. I want to use the Cottonwood with the Raspberry Pi. I have found posts where people have got it to work and have found posts where they cannot.
So I wonder if my assumptions are correct:
1) The UART version is best for the RPI
2) I connect the TX to RX and RX to TX and use the 3.3V for power
I then should be able to read data using the RPI? Has anyone here successfully used a PI with the Cottonwood and could give me some pointers before I purchase one?
Thanks in advance for any help.
