RFD900X Digital Radio Module Factroy 40km Long Range Data Link Modem Manufacturer Flight Control Transmission Radio Drone Supply Transmission UAV UAS UGV US
RFD900 + and RFD900X main difference is that the RFD900 + can only be one-to-one, while the RFD900X can be one-to-many, suitable for clustering, group control and other projects
The following cables of FTDI are compatible with RFD900 modems. FTDI cable pin 1 connected to the RFD 900 connector pin 1 of the connector.
To power the modem with a +5V USB power supply, a jumper needs to be connected between pins 4 and 6
To power the modem from an external +5V power supply, connect the power supply to pins 2 and 4.
