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
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
The RF Modem interfaces to the host computer via an RS232 connection using a standard DB9 connector as
shown in the diagram below.
