• Manufacturer Part Number: BIM2
• Description: 433mhz high Speed FM Radio Transceiver Module
• Manufacturer: Radiometrix

AF
This is a buffered and filtered analogue output from the FM demodulator. It has a standing DC bias of
1.2 volts and 400mV
impedance should be >2k
TXD
This DC coupled modulation input will accept either serial digital data (0V to Vcc levels) or High level
linear signals. Input impedance is 10k .
TX select
Active low transmit select. 10k
RX select
Active low receive select. 10k
Note: Loop test allows the receivers to monitor the transmitted signal. The receiver will not receive
external signals whilst the TX of the module is enabled.
Vcc
+ve supply pin. +3.0 to +5.5 volts @ <20mA . The supply must be clean < 20mV
coupling capacitor and 10
Weight: 5g (typical with pins)
