RFID Receiver and I2C Adapter with USB Interface for WiPy2 & LoPy

Hi, i search to make this run but i don’t find howto.

I have put a wipy (with fresh update) on it. I try to read uart by this command:
from machine import UART
uart = UART(1, 9600)
uart.init(9600, bits=8, parity=None, stop=1)

but i get None everytime. I have try to see with an oscilloscope the data wich be send between your two electronic part, but i have see some data but this rarely occur. After 30 min of test, i don’t see anymore data on the RX line.

Can you explain wich test i can do to understand howto read an RFID tag please?

Any documentation?
