LICHIFIT 134.2K AGV RFID Module FDXB Animal Ear Tag Reader TTL FDX-B ISO11784/85 Long Distance Card Reader Module

Great little board. You'll need some basic soldering and electronics skills but had it reading a test chip 20 min after opening the box. Haven't followed the instructions to tune the supplied antenna yet, and it reads from 3" away. If you're having trouble getting any output, a blue LED on the board flashes when it reads a compatible chip to let you know at least that part is working. Highly recommend doing a proof of concept using an ftdi adapter before wiring it up to an ESP or Arduino. Came with clear instructions and advice for DC vs AC power supply and how to reduce noise and has an email to send questions. (Haven't had any yet.)

Easy to use. Just with arduino set a Serial communication 9600 speed. Serial1.begin(9600, SERIAL_8N1, 25, 33); // Just change the pins

I tried different power supplies, voltages, and antennas. The antenna always had to be within 1/2" of the RFID/FDX-B chip to read and it was very unstable.

8-10cm de alcance sin problema con chip subcutáneo sin inyectar. Si es para algun proyecto DIY recomiendo poner un tag en un collar ya que el alcance dentro de la piel se reduce como es lógico. Siguiendo las instrucciones para ajustar los jumpers todo perfecto.

Funktioniert tadellos, allerdings sollte man schon Erfahrung haben im dekodieren der übermittelten Pakete. Funktioniert auch zuverlässig mit Powerbank (5V) als alleinige Stromversorgung.
