DX3 SMART DSMR 3CH TX w/SR315 (SPM2340)

DX3 Smart DSMR 3-Channel Transmitter with SR315 Receiver is a compact three‑channel radio system designed for precise control of RC cars and trucks. It pairs a DSMR‑capable transmitter with the SR315 receiver to deliver reliable steering and throttle input for ready‑to‑run models, and its Smart technology opens the door to telemetry and advanced programming when used with the Dashboard app.

To access the Dashboard features, add a Bluetooth module to the transmitter and pair it with the free Spektrum Dashboard app on a compatible iOS or Android device. Real‑time telemetry, alarms for temperature and voltage, and expanded transmitter options help protect components and tune performance. The system works with telemetry‑enabled receivers and Smart ESCs, and is well suited for RTR platforms from ARRMA, Axial and Losi. Optional accessories like a Smart Phone Mount make it easy to attach a device to the transmitter for on‑the‑go monitoring.
