Spektrum DX3 SMART DSMR Transmitter SPMR2355

The Spektrum DX3 SMART DSMR Transmitter Only: U-34 Hydro, part number SPMR2355, is a transmitter-only radio-control product from Spektrum. It is identified for the U-34 Hydro and uses the DX3 SMART DSMR designation stated in the product name. This gives hobbyists a clear way to identify the required transmitter when checking their equipment, planning a project or comparing part numbers. The product name also makes clear that this listing concerns the transmitter itself, rather than a complete radio-controlled model package.

As supplied, the item is described as transmitter only, so no receiver, model, battery, charger or other accessory is assumed to be included. The U-34 Hydro reference provides the relevant model context, while SPMR2355 is the key part number for checking records and distinguishing this item from other Spektrum transmitters. The SMART and DSMR terms are retained exactly as part of the stated product designation. No further specifications, controls, dimensions or included accessories are provided in the supplied information.
