MRServo is a low-cost, low-profile, slow motion model railroad switch machine. Using inexpensive and small RC servos, MRServo provides a cost-effective way to add slow-motion turnouts to your layout. For accessory contacts, see MRServo-2. For power routing applications, see MRServo-3 with its PowerFrog technology.
MRServo is available in three versions, to meet different needs and price points.
Each kit comes complete with the fully assembled control board, servo, hardware, throw wires, and a piece of heavy-duty mounting tape. A controller-only version is available if you want to provide your own servo and hardware. A "Crossover" option is also available to control two turnouts simultaneously using a single control board (-1 and -2 versions only).
With a little extra circuitry, MRServo can be made compatible with most Digital Command Control (DCC) stationary switch machine decoders. See details at "MRServo for DCC".

Need a slower or longer throw than the conventional MRServo design offers? We are able to customize the MRServo software to some extent and can provide custom-programmed units for a small fee. Email us and let us know your requirements, and we will be in touch about what we can do.
The latest MRServo hardware design files and source code are now available at GitHub!
