# DCCMFL1616
![DCCMFL1616](./images/DCCMFL1616.png)
The DCCMFL1616 is a family of DCC Multi-Functional locomotive decoders based on the ATtiny1616 microprocessor.
The DCCMFL1616 is a family of DCC Multi-Functional locomotive decoders based on the ATtiny1616 microprocessor.
The basic schematic for all the controllers are the same except the interface / connector to the locomotive.
All electronics designs were created with KiCAD and are licensed under the [EUROPEAN UNION PUBLIC LICENCE v. 1.2](./LICENSE)
The firmware to run these decoders is available [in antother repository on our git-server](https://git.schauaus.at/Fahrzeugsteuerungen/DCCMFL-Firmware).
## Versions available
### DCCMFL1616_660
The DCCMFL1616_660 is designed according to [NEM standard 660](https://www.morop.org/images/NEM_register/NEM_E/nem660_en_2022.pdf) and to be used with an 21MTC interface.
