Finally, connect the pins to your Arduino
GND goes to ground
Vin goes to 5V
Data to I2C SDA (on the Uno, this is A4 on the Mega it is 20 and on the Leonardo digital 2)
Clk to I2C SCL (on the Uno, this is A5 on the Mega it is 21 and on the Leonardo digital 3)
RST to digital 4 (you can change this pin in the code, later)This matches the example code we have written. Once you get this working, you can try a different Reset pin (you can't change the SCA and SCL pins).

il y a une erreur non corrigée :
"l faut brancher le récepteur directement sur les ports GPIO comme suit : 3.3V sur la broche 1, Masse sur la broche 6 et Sortie sur la broche 12 (la broche 1 est la plus pres de la carte SD).
