Description

LocoNet command station with WiFi

  • WiFi and main MCU is ESP32 board (Lolin32 Lite).
  • DCC part is done with L298N for both main and programming track + 74HC04 hex inverter log logic level inversion.
  • LocoNet part uses usual in DIY LocoNet community LM393 comparator with resistors adapted for 3.3V levels.
  • 2 LocoNet jacks with power for throttles and accessory decoders, 1 LocoNet jack for booster (with DCC signals)

PCB is located in PCB_100x50_fab file, its size is 100x50mm, fits usual economic option of many fabhouses (JLCPCB, PCBWay).

Firmware is developed here
