DT / DelTang DSM2 Low Voltage Micro Receivers for Land-Based Use

Rx41d-v5 | Rx43d-x-v5 | Rx45 | Rx47-v5 | ADD1 | ADD2 | MAG3 | PROG3

The 'v5' receivers are UK designed and manufactured DSM2 ultra micro 2.4GHz receivers for low voltage (up to 6V) land based applications: cars, boats, and trains. All are compatible with Spektrum DSM2 Air and DSM2 Surface modulation, the Rx47 also supports DSMX. All have a combination of ESC and servo switch outputs which may be programmed to suit your need. Either a stick type transmitter or PROG3 may be used for configuring the receiver settings.

In the receiver descriptions below:

  • H is a reversible H-bridge output,
  • F is a non-reversible output and
  • P is low-current (8mA) servo or switch output.

F outputs can supply up to 2A but the H outputs are lower current. The current capacity of a H output can be boosted and 2 x F outputs can be combined to make an additional H output using one of the add-on amplifier boards: ADD1 for 0.8A and ADD2 for 3A.

The MAG3 magnetic connector board is ideal for making low weight, low force electrical connections.

More information about the DT 'v5' receivers is available on this page. See DSM2 Transmitters for compatible transmitters. Take a look at the Rx6x range of receivers for high voltage (up to 16V).

Rx41d-x-v5 DSM2 Micro Receiver with Bi-Directional ESC
(Top | Rx43d-x-v5 | Rx45 | Rx47-v5 | ADD1 | ADD2 | MAG3 | PROG3)

Rx41d-v5 is a DSM2 compatible micro receiver with one 500mA H-bridge reversible ESC output (H), 2 x 2A non-reversible ESC outputs (F) and 3 x servo/switch outputs (P). The H output can be boosted to 0.8A or 3A and the 2 F outputs may be converted to a H. The P outputs may be used to drive servos or used as low current (8mA) switches, e.g for LEDs.

The receiver is available as a bare board with 1.27mm pad space and as a wired version. The latter has lead-out wires installed for battery and motor (H output) and has heat-shrink covering for protection. Please contact us if you need lead-out wires attaching to the F or P outputs.

Rx43d-x-v5 DSM2 Micro Receiver with Bi-Directional ESC
(Top | Rx41d-v5 | Rx45 | Rx47-v5 | ADD1 | ADD2 | MAG3 | PROG3)

Rx43d-x-v5 are a set of DSM2 compatible micro receivers with a combination of H-bridge reversible ESC (H), non-reversible ESC (F) and servo/switch outputs (P). The same PCB and components are used for all variations and the number type of outputs is determined by the loaded firmware.

Rx43d-4-v5 is supplied with ADD1 which must be used for the 4th H output to supply 0.8A. Without the ADD1 connected, the 4th H output can provide only 8mA. Other receivers in the Rx43d-x-v5 range (1, 2 & 3) are not supplied with an ADD1 - ADD1 or ADD2 may be additionally purchased to either increase the current rating of an existing H channel or to convert 2 x F channels into an H channel.

Programmer for Rx4x 'v5' and Rx6x Receivers (PROG3)
(Top | Rx41d-v5 | Rx43d-x-v5 | Rx45 | Rx47-v5 | ADD1 | ADD2 | MAG3)

PROG3 is used to change settings in Rx4x 'v5' (from v5.10) and Rx6x (from v6.10) receivers. Changes are made on PROG3 and sent through to the Rx with the push of a button.

All Rx4x 'v5' receivers can be programmed using a standard DSM2 transmitter - i.e. one with control sticks. Receivers with firmware version at v5.1.0 and up can be programmed using this programmer. Instructions for using PROG3 are located here.

All current stock has firmware with support for PROG3.
