SMART RADIO TRANSCEIVER  
RF650  
6 Evaluation Board  
Direct RS232 Interface to PC  
Accepts 433 or 868MHz Modules  
Easy configuration with downloadable  
software tool  
LED Indication of transmission  
Accepts a range of Antenna Sockets  
Supply Voltage 5 - 12Vdc  
The RF650 evaluation board provides a reliable proven host board for development with the RF650  
module. A single board is supplied, no RF650 module is included with the board and the antenna socket  
is not fitted. This enables the board to be used for either the 433MHz or 868MHz module with a range of  
antenna socket types.  
6.1 Connections  
6.1.1 Power  
The evaluation board requires a 5 - 12Vdc power source. The maximum operational supply current is <50mA.  
Power is applied to the two way screw terminal labelled ‘CN1A_B.’ The left hand side of the screw terminal is  
GND (nearest the DB9 connector).  
6.1.2 RS232 Connector  
The RF Modem interfaces to the host computer via an RS232 connection using a standard DB9 connector as  
shown in the diagram below.
