Version 1.0

The DS205 – I2C reverse loop module has connections for track signal, section A, section M (middle) and section B. Sections A and B have current detection and the module acts as feedback decoder for these two sections. This module has 3 relays, for each section one relay. The connected Arduino needs to take care of controlling these relays depending on the feedback information received. It has the same pinout as the PCA9685 PWM module and can therefore be connected in the same way. For connecting this module to Loconet, the DS104 – Lnet I2C interface can be used. Starting from software version 0.91 the reverse loop functioning is included in the sketch so the module will only act as feedback decoder if necessary.

The DS205 – I2C reverse loop module is sold as do it yourself project containing PCB and all components.

Built time for an experienced tinkerer: 30 ~ 40 minutes.

The DS204 – I2C sensor module is an 8 channel sensor module. It has the same pinout as the PCA9685 PWM module and can therefore be connected in the same way. For connecting this module to LocoNet, the DS104 – Lnet I2C interface can be used.

The module has 8 triple pins providing 5V, GND and an IN pin for connecting infra red sensor modules (active high) or hall sensors (active low) like the 44E hall sensor.

The module has 2 jumpers to determine if the input pins should be high by default (needed for 44E hall sensor) or low in two sets of pins: J11 controls ports 1 to 4 and J12 controls ports 5 to 8.

The DS202 – I2C mass detection module is an 8 channel mass detection module. It has the same pinout as the PCA9685 PWM module and can therefore be connected in the same way. For connecting this module to Loconet, the DS104 – Lnet I2C interface can be used.

The module has one common pin labeled C and each detection circuit has it’s own detection pin. It detects a connection between each detection pin and the common pin so it can therefore be used with reed contacts or switches.
