Description

DCC/RailCom Function Decoder for Minitrix Passenger Cars

README

RTB_D13

My Homebrew D13 LED decoder is a drop in design for Minitrix (#15791) coach with no mechanical modification required. The decoder is designed to integrate into the RTB digital control infrastructure.

Hardware

The current PCB layout uses SMD footprints with 0.5mm pitch and mainly 0603 parts. Reflow soldering is recommended whereas handsoldering will be difficult.

PCB

• 4-layer PCB, FR4, 1mm
• CPU: AVR64DA48
