Hello, how many multiple readers can i handle with an arduino uno? is it possible to use this reader (multiple readers) with a Raspberry PI? thank

Hi Dear Customer, this reader uses the serial port. we suggest the software serial to readers, and hardware serial port for the PC display. So you can connect multiple readers. Bill

Anyone know what Encoding Scheme (Manchester, BiPhase or PSK) is supported by this module?

Hello, I am using the 125kHz 5-tag sample pack and neither this module or the normal sized LF module can read any of the tags with the sample code from the wikipedia and the github repository. Please advise...

Hi there, I suspect you use the arduino uno D0/D1 for serial print and rf module communication as well. it is conflict. so please use the D2/D3 for rf module communication and D0/D1 for serial monitoring. Please send mail to techsupport@seeed.cc. I will forward the code to you. thanks.

Hello, can anyone tell me: 1. Which IC is mounted on the module? 2. What's the pinout of the module? I guess V is 3,3-5V, G is GND, RX and TX belong to the UART. But what about RST and S? 3. How to interface with the module? I can't read anything from the UART when bringing a RFID-Tag into the range of the reader. Thanks

I did a little reverse engineering by myself, so: 1. There's no special RFID-IC on the module. It's a Microcontroller from ST: STM8S003F3 2. The RST-Pin is the RESET of the Microcontroller. I still don't know what the S-Pin is for.. 3. Now I can read from the UART. The supply voltage was too low.. My fault. But why is it reading just four numbers instead of five? I know that there are five numbers stored on my RFID-Tags.

I noticed in the library that there is a buzzer output from the chip that is not broken out. Could you provide the datasheet so that I could look into adding that buzzer? Thank you.
