MR005 is a 7 channel DSM2/DSMX
compatible receiver designed for model
railway layout control. It has 7 JR/Futaba
style pin sets to which servos or LEDs may be
connected. MR005-7S has 7 servo outputs,
MR005-7X has 7 on/off outputs (0V / 3.3V)
to which LEDs may be directly connected as
there is a 220 ohm series resistor on the receiver board. MR005 with a combination of servo and on/off
outputs, or different R/C channel to receiver output mappings, is available to special order. MR005 is
small (30x18x11mm) and it weighs 4.5g.
Each MR005 output is controlled by one R/C channel (e.g one switch on Tx27v2). Receiver state (servo
position or on/off setting) is saved once a minute and restored when the receiver is switched on. This
allows MR005 to be switched on without the transmitter being switched on.
MR005 requires Binding
not go into bind mode if the transmitter is not switched on. Once bound, the transmitter should normally
be switched on before the MR005.
The MR005 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 an
enclosing box and clear of any metal. The active part of the aerial is the last 30mm and this needs to
'see' the transmitter. The MR005 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 at all positions around the layout.

Features

Compatible with all DSM2 and DSMX transmitters with up to 10 R/C channels (only 7 used in the
standard MR005 versions, both Micron model rail and aero model stick type transmitters.
3.45V to 8.4V working voltage range - 5 NiMH cells is ideal.
All outputs have a 220 ohm series resistor which allows direct connection of a low-current LED.
Servo outputs are reversible and end-points may be adjusted.
Outputs maintain current setting on signal loss and are saved every minute so that they can be
restored next time the receiver is switched on.
The CPU LED is repeated to P8 (rear JST-ZH socket or solder pads, depending on the MR005
version).

Connections and Indicators

MR005 has 7 sets of output pins which can be used for servos (MR005-7S) or LEDs for colour light
signals or trackside lighting (MR005-7X). The pin sets, numbered from the top of the diagram below, are
0.1" pitch to take standard R/C plugs.
