CMMME Prima - DCC Decoder - 32 Outputs - Servos / LEDS / Relays.
Introducing Prima - Our most advanced decoder.
Prima is our third product to market Currently, there are no other commercial solutions that allow you to operate 32 outputs for as little as £2.50 each. Our previous two were based on Arduinos. However, whilst both reliable and cost-effective, ease of operation was limited.
Changes to configuration would have to be done via editing code via a computer and uploading via a physical connection – not suitable for layouts where units are mounted underneath a layout.
Our easy-to-use web interface allows you to connect to it via its own WIFI access point, or alternatively connect Prima to your own WIFI network.
Once you have made your changes using the manual found here , saved and restarted your decoder, you’re ready to go!
Prima allows for both physical and DCC control of these outputs which can be assigned to either a LED, Relay or Servo, with the ability to have a physical button or DCC command, giving the ability to control multiple outputs with the same input.
An example of this would be to push a button, changing the direction of the servo to change a turnout, at the same time the relay would change the polarity of the track and illuminate a led for a control board. All done with one button push or DCC command.

Overview
Hardware
Prima is made up of four components.
- An Esp32 development board, providing the processing power and connectivity for all interfaces.
- (2) PCA9685 12 bit PWM drivers.
- An in-house designed PCB. Allowing for the above to be interfaced together. Including a DCC interface, 5v input and 16 terminals for physical buttons. The DCC input is opto isolated protecting the decoder from higher voltage track power.
- A 3d printed mount.
- A 5V 2A DC Power Supply.
Software
A key focus in the development of the Prima was to ensure ease of control and setup.
Previous hardware developments by ourselves have involved editing Arduino code, whilst we ensured this was easy to do, we understand this can be overwhelming and time consuming.
With Prima all configuration can be done via a web browser, simply by connecting your phone, tablet, laptop or computer to the WIFI network created by Prima.
Once connected, you have the ability to configure each of the 32 outputs.
Requirements
A 5V 2A DC power supply.
A phone, tablet, laptop or computer with WIFI connectivity.
