Micron MR001 DSM2/DSMX Receiver for Land-Based Vehicles

Click on image for a larger version.
Micron MR001 2.4GHz DSM2/DSMX Receiver

A small (30 x 18 x 11mm) 8 output DSM2/DSMX compatible receiver for model railway use on live-steam and large battery electric locos. It can drive speed controllers, servos and LEDs (auto-directional lights and manually switched from the transmitter). The dimensions allow it to fit easily into many 32/45mm steam or diesel locomotives. MR001 is a good replacement for the Deltang Rx102 receiver.

The voltage range is 3.45V to 8.4V so is best powered from a 4 or 5 cell NiMH battery for live-steam or from the 5V BEC speed controller output for battery electric locos.

MR001 is compatible with all Micron model rail transmitters, with Deltang transmitters and Spektrum stick-type aicraft transmitters (e.g. DX6*). Selecta is supported for use with Tx22 and Tx24. Selecta is disabled by default but easily enabled using the supplied jumper plug. MR001 must be bound to a transmitter before use; some MR001 require a jumper plug across signal pins 5 & 7 to put them in bind mode, others automatically enter bind mode if a previously bound transmitter signal is not found within 5 seconds of switch on.

Two versions of MR001 are available which differ in the method of configuration:
MR001a:Fully programmable using a Micron model rail or stick type transmitter - see the MR001a user manual for details
MR001b:Servo reversing and travel adjustment using jumpers on servo pins, no programming
The default output configuration for both versions is:

  • 5 servo outputs (ch1...ch5)
  • 2 switched front/rear LED outputs
The version and bind type is identified on the label affixed to the bottom of the circuit board: e.g. 'MR001a (ab)' is a type 'a' supporting auto bind and 'MR001a (mb)' is a MR001a that can only be bound using the jumper plug.

Two aerial types are available:

  • single aerial (manual bind only) - 30mm antenna at the end of 60mm coax (total length = 90mm)
  • twin 90mm aerials with diversity reception; the receiver takes data from the aerial with the strongest signal - useful on garden layouts with lots of obstacles, e.g. bushes, rockery

7 outputs are available at the front of the receiver using standard 0.1 inch pitch JR/Futaba pins and there is 1 output at the rear. Twin aerial diversity receivers have a JST-ZH socket for the 8th output, single aerial receivers have solder pads. MR001a outputs can be configured for servo or 0V/3.3V switched, MR001b outputs are fixed at the standard configuration (other configurations of servo and switched outputs can be provided to special order).

See the MR001a user manual or MR001b user manual for further information.

Weight: 4.5gm, dimensions: 30mm x 18mm x 11mm.
