 To control the layout I will need power supply, booster, command station, loco decoders, accessories decoders, busy detectors and a communication module for PC.

   * Found nice cheap MP3 players to use with [[electronics:dcc:loco_decoder|Loco Decoder]] or with [[electronics:dcc:accessory_decoder|Accessory decoder]]. These are [[https://www.dfrobot.com/wiki/index.php/DFPlayer_Mini_SKU:DFR0299|DFPlayer Mini]] and [[https://www.amazon.com/U-Disk-BY8001-16P-Player-Arduino-Module/dp/B01MZYAVRF|BY8001-P16]]. Modules are small, can drive up to 3W speakers, can be connected to MCU. Support spot sound insert feature, but this is achieved by pausing main sound, playing spot insert and resuming main sound.

   * Universal DCC decoder, that can be used as Loco or Accessory or Function decoder is described fully in Model Railroad Hobbyist March 2017 #85 magazine. Decoder is based on Arduino and cheap additional components to receive power and signals from DCC bus. Also computer controlled Arduino based Command Station with integrated Booster is decribed there. Then the PC communication module is not necessary, since Arduino will act also as that. All the software and firmware used is also open source DCC++ project. I should compare component prices and perhaps redo all the hardware with STM32 chips. Anyway I am not intended to use bare Arduinos and shields and will make own PCBs to reduce size and adapt for my rolling stock shapes and needs.
