Weet iemand welke pin van de onderstaande 7 ik op de gpio van een arduino moet aansluiten? Ik zoek namelijk de data pin. Het is een radiometrix rx2-433-14. (Bron: https://www.radiometrix.com/files/additional/TX2RX2.pdf)
RF in (pin 1)
50Ω RF input from the antenna, it is
DC isolate internally. (see antenna
section for suggested antenna/feeds).
RF GND (pin 2)
RF ground pin, internally connected to
the module screen and pin 4 (0V). This
pin should be connected to the RF
return path (e.g. coax braid, main
PCB ground plane etc.)
CD (pin 3)
The Carrier Detect may be used to drive an external PNP transistor to obtain a logic level carrier detect
signal, see test circuit. If not required it should be connected to pin 5 (Vcc).
0 Volt (pin 4)
Supply ground connection, connected to pin 1 and screen.
Vcc (pin 5)
+ve supply pin. +3.0V to +6.0V @ <17mA . The supply must be clean < 2mVP-P ripple. A 10µF decoupling capacitor and 10Ω series resistor is recommended if a clean supply is not available.
AF (pin 6)
This is a buffered and filtered analogue output from the FM demodulator. It has a standing DC bias of
1.2V and 400mV P-P base band signal. It is useful as a test point or to drive linear decoders. Load
impedance should be > 2kΩ and < 100pF.
RXD (pin 7)
This digital output from the internal data slicer is a squared version of the signal on pin 6 (AF). It may
be used to drive external decoders. The data is true data, i.e. as fed to the transmitter. Load impedance
should be > 1kΩ and < 1nF
