Micron Radio Control MR001d Instruction Manual

Micron MR001d 2.4GHz DSM2/DSMX Receiver (from v1.2)
This document is regularly updated and the most recent version may be found online at

The MR001d receiver is well suited for use in large scale live-steam or
large scale battery powered locos. It operates on 2.4GHz using the
Spektrum DSM2 or DSMX protocols; thus it operates just like any other
DSM2/DSMX receiver but includes some useful features for model railway
control. The MR001d is small (30x18x11mm) and space for it is easily
found in most locos.
The MR001d free-air range, when used with a Micron low-power transmitter, is 50m-60m and
approximately 200m when used with a full-power (100mW) transmitter. This range will be reduced
indoors due to absorption by furniture / fittings and reflections from metal surfaces. Range is also
reduced if the receiver aerial is in a metal enclosure. Ideally, the aerial should be placed outside the
vehicle body and clear of any metal. The active tip of the extended aerial needs to 'see' the transmitter
so should be placed through a hole in the vehicle body - e.g. into the cab space. The receiver aerial
should not be cut short or made longer as this will affect operation of the receiver. It is important to
perform a range check after installation to ensure you have full control of your loco/vehicle at all
positions around the layout.
Features
Compatible with all DSM2 and DSMX transmitters with up to 10 R/C channels, both Micron model
rail and aero model stick type transmitters.
3.45V to 8.5V working voltage range.
11 outputs which can be configured for servo/ESC or 0V/3.3V low-current switched ports; 7 ports
are at the front with 'standard' 0.1" pitch connector pins, ports 8 to 11 are on an optional JST-SH
connector at the rear.
Supports the Selecta
re-bound to change Selecta switch position.
The default configuration provides auto-switched front and rear LED lights on P6 and P7 controlled
by the throttle channel.
Receiver on-board LED can be repeated to any non-servo output (this is called the LED2 function).
All functionality may be configured by programming using a a suitable transmitter (most Micron tx
or a stick type model aircraft tx).
Connections and Indicators
MR001d has 7 set of JR style 0.1" pitch output pins, labeled P1 to P7 on the diagram below. Ports P8 to
P11 are on the optional JST-SH connectors at the aerial end of the receiver. Although the JST-SH
socket has 3.3V power, this is insufficient for powering a servo which must use an external regulator or
by power directly from the battery.
MR001d can be powered from a battery of 3.45V up to 8V; use of a 4 or 5 cell NiMH rechargeable
battery or the 5V regulated output from a speed controller is typical.
MR001d contains 4 configurations
by programming the receiver. The default configuration has servo outputs on P1 to P5, front/rear
lighting on P6 and P7, and switched outputs on P8 to P11 - see the Configurations table at the end of
this document. Other output configurations are available on request.
