Guides

WDP Remote Controle

ESP32 · U2.6 · Default 4MB with spiffs

Remote controller for Win-Digipet – select a train and drive it. Function buttons can also be activated.

DCC Servo Dekoder

ESP32 · U3.1 · Default 4MB with spiffs

DCC Servo Decoder – controls up to 16 servos. Simple and intuitive configuration of each servo’s start angle, end angle, and movement speed. It is possible to configure up to 4 positions per servo. The DCC Servo Decoder can now automatically release the PWM signal to a servo once the programmed position has been reached. mark "Release PWM"

DCC/MQTT Lysdekoder

ESP32 · U2.4 · Default 4MB with spiffs

Controls programmable LED strips. Can be controlled via both DCC and MQTT. Supports up to five LED strips. Each LED strip can have up to 50 LED's.

DCC/MQTT Light Dekoder

ESP32 · 3.2 · Default 4MB with spiffs

Control of programmable LED strips with current monitoring. Can be controlled via both DCC and MQTT. Up to 5 LED strips with up to 50 LEDs per strip. An INA226 continuously measures voltage, current and power, which are displayed on the OLED and in the web configuration. This makes it easy to monitor the total current consumption and prevent overload.

DCC Layout module

ESP32 · 08.9 · Default 4MB with spiffs

DCC Layout Decoder is a flexible accessory decoder for functions needed on almost every model railway: turnouts, signals, building lights and other devices that need to be switched on and off. Unlike many traditional and often more expensive decoders, the DCC Layout Decoder is easily configured using a web browser. The system consists of one DCC Basic Module, to which up to 4 DCC Layout Modules with 8 outputs each can be connected. This allows control of up to 16 turnouts/signals or 32 individual outputs – or any combination of them. Outputs can be configured as Momentary (K83) or Permanent (K84). Permanent outputs can operate as normal On/Off switches or as Light outputs, where brightness and effects such as Fade, Blink, Slow Blink, Flicker and Beacon can easily be selected in the web configuration.
