Arduino MRR Speedometer
In model railroading, a speedometer is a useful tool for measuring the scale speed of locomotives, ensuring realistic operation and consistency across a layout. By placing a digital speedometer along a section of track, hobbyists can accurately gauge how fast their trains are moving in scale miles per hour (SMPH). This is particularly important for prototypical operation, where freight trains should run at slower speeds than passenger trains. Some DCC (Digital Command Control) systems even incorporate speed measurement features, allowing users to fine-tune locomotive performance. Whether for fine-tuning acceleration curves or matching the speeds of multiple units in a consist, a speedometer enhances realism and control in model railroading.
- Scale: Z, N, HO, S, O, G
- Kits include v2 Components
- Bi-Directional
- DC or DCC
- Displays Scale Speeds
- Speed match your DCC locomotives
- 4 Different Sensor configurations
- Compact and portable
- On-board Status LEDs.
- It requires a 5v supply, USB, or direct for the Nano.
I would like to purchase one or more of the speedometer kits but I’d like to mount them permanently on the fascia. Is there a bezel that you’re aware of to fit the LED display?
Thanks in advance.
Craig, there are a couple of ways to mount these LCDs.
1. Amazon sells a 3D printed bezel (https://amzn.to/4i3PGml) that you can use double-sided tape to mount.
2. There are tons of 3D files you can download and print. (https://wcmrr.com/I2C-LCD-faceplate).
3. Is there a possibility that I could print one for you.
I am confused about acquiring an Arduino MRR Speedometer. When I select the order online button, I get this message “No Results Found. The page you requested could not be found. Try refining your search or use the navigation above to locate the post.” I researched Arduino and found various kits but nothing specific as a Model Railroad Speedometer. I am starting a new layout since moving and would like to incorporate one of these where it would be hidden.
I’m fairly new in model railroading so I might be missing something but would appreciate your help. On my last layout I used a tape measure and a timer. This looks significantly better.

Hey Bill, thanks for reaching out. Right now, we are out of stock again. When these do go in stock, they don’t last very long. I am struggling to get one of the chips that I need to complete this build. I don’t have an ETA from China right now, I’m not that special 🙂 I have your information and will let you know as soon as I can build more inventory.
