DSMX SRXL2 Serial Micro Receiver

Spektrum SPM4650 DSMX SRXL2 serial micro receiver

1.4 grams. Smaller and lighter than any previous Spektrum serial receiver – and with more functionality than its predecessor, the SPM4648. The SPM4650 uses the SRXL2 protocol with a lightning-fast serial link of up to 20 channels and two-way communication with the flight controller: telemetry and setup directly from your Spektrum transmitter via Forward Programming, VTX Setup or Text Gen – over a single signal wire.

Perfect for DIY builders: the connector comes unmounted, so you can solder directly to the board and save weight – or fit the connector and use the included lead. Two long coax antennas give diversity and a strong signal, even in models with lots of carbon fibre and metal. The bind button works before and after power-up, and the voltage range is wide: 3.3-8.4 V.
