MR601a is a 2.4GHz DSM2/DSMX receiver which includes one integrated 1.2A reversable controller for brushed motors (ESC) plus 5 auxiliary outputs (2xF, 3xP) for lighting, sound trigger, couplers, etc. It can be used with any Spektrum DSM2/DSMX compatible transmitter; this includes all of the Micron model rail transmitters or a stick model aircraft type transmitter.

MR601a is 22.5 x 11 x 5 and weighs 0.9g without leads. The voltage range is 2.7V to 13v and the 1.2A motor current rating makes it suitable for 00/H0, 7mm narrow gauge and smaller Gauge 0 locos. MR601a is available as board-only for you to add wiring or with a range of pre-wired leads. The standard output configuration is described on the Outputs tab. If the wiring or configuration options do not meet your needs, please contact us to discuss your requirements.

An enormous range of programming features are provide to enable you to customise the operation of MR601a to suit your model. The current firmware version is 1.8.1. See MR601 Programming (v1.5) for full details or the user manual for brief information. Access to programming is either via a stick type transmitter or one of the Micron model rail transmitters. A stand-alone programmer with web interface is in development.

The receiver is supplied either as a bare board or with wiring options and heatshrink covering as specified in the menus below. MR601a is available only with a short wire arial. If the receiver is to be used with a metal bodied vehicle, it should be mounted so that the aerial wire can be fed through a small hole to the outside of the body or into the cab space.

The default behaviour of the P outputs and F switches are defined on the Configuration tab. F switches are best used for sound card triggers - select configuration #2 or #3 to match your transmitter controls. If you need more than 2 x F switches, a selection of small FET buffers are available to convert P into F. The MR601a side connection pads for F and P are small and close together. If you are not confident of micro soldering, please order MR601a with one of the wiring options or, contact Micron if none of these match your need.

Selecta, Throttle and Wiring Options:
Selecta:

Selecta (loco selection with Tx22, Tx24, etc)

Throttle Control:
ESC PWM Frequency:

16kHz PWM is ideal for most motors, especially coreless and small iron core; 500Hz or 250Hz is better for a larger iron core motor (better throttle response and reduced heating). The PWM frequency can be change using a power-on-change or by programming.

Power/Motor Leads:
P outputs:

These are logic level 0V/3.3V outputs, mainly used for LED lighting. The default configuration has auto-switched forward and reverse lighting on P1 and P2 with P3..P6 switched using transmitter controls.

F switches:

If sound trigger wiring is selected, specify the transmitter controls used for sound in the 'Receiver Config' menu below. Other wiring options and tx control mappings are available, contact Micron to discuss your requirements. See the Outputs tab for information on output usage.

Receiver Config:

The receiver configuration may be changed if sound card triggers selected for the 'F' options above. Specify the transmitter controls to be used triggering sounds. If none are appropriate, contact Micron to discuss your requirements.

LVC:

The receiver has a low voltage cut-off (LVC) facility which stops the motor when the battery has reached its discharge voltage. The default setting is for LiPo batteries. If you are using NiMH, the LVC should be disabled - see Low Voltage Cutoff tab.

Heatshrink Cover:

Select 'cover supplied loose if you intend to add lead-out wires to the receiver; otherwise select 'applied to board'. If you want the receiver protected against accidental contact with metal parts, please select the 'heatshrink applied' option.
