Pin Descriptions
RF GND (pin 1)
RF Ground pin is internally connected to pin 4 (0V) This pin should ideally be connected to the nearest
ground plane (e.g. coax braid, main PCB ground plate etc.)
RF OUT (pin 2)
50Ω RF antenna output. To achieve best results the antenna impedance must match that of the module.
VCC (pin 3)
+Ve supply pin (3.0 to 9.0 volts). The module will generate RF when VCC is present. It is strongly
recommended that a 100nF capacitor decouples the supply rail as close as possible to this pin.
GND (pin 4)
Supply and data ground connection, connected to pin 1.
Data IN (pin 5)
This input has an impedance of 47KΩ and should ideally be driven by a CMOS logic drive or compatible.
The drive circuitry should be supplied with the same supply voltage as the Tx module.
