# DCC-Lokdecoder
|
|
## Description
|
|
DCC multifunction decoder for H0 locomotives
|
|
## Features
|
|
- 1 motor H-bridge output
|
|
- 3.6 A peak current
|
|
- PWM frequency configurable (1-40 kHz)
|
|
- overcurrent and temperature protected
|
|
- 10 function outputs
|
|
- 115 mA per output
|
|
- F0f, F0r, AUX1 and AUX2 are dimmable *todo*
|
|
- mappable to F0-F12 function keys
|
|
- DCC asymmetry can be detected (for automatic brake control) *todo*
|
|
## Hardware
|
|
- 4-layer PCB esigned in KiCAD
|
|
- fairly standard components (available from Digi-Key, Farnell, Mouser, etc...)
|
|
- hand solderable (I did it too)
|
|
- 4 debug LEDs
|
|
## Firmware
|
|
- Arduino compatible programming (behaves like an UNO)
|
|
- DCC decoding by [NMRA](https://github.com/mrrwa/NmraDcc)
|
|
|
|
## JMRI integration
