Version 1.0

The DS208 – I2C hub can be used to connect multiple I2C modules to one bus. The module has it’s own 5V voltage regulator circuit and level shifters on the module allow the module to be connected to either 3.3V or 5V I2C bus.

The DS207 – I2C relay module is an 8 channel relay 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 two common pins labeled C1 and C2 and each relay has it’s own output pin (Normally Open connected to C2, when activated connected to C1). To minimize power consumption the module is equipped with low current LEDs but if no indication is needed, these LEDs can be turned off by removing jumper J2.

The DS207 – I2C relay module is sold as do it yourself project containing PCB and all components.

The DS206 – I2C switch module is an 8 channel switch module which uses 2 IC’s of type ULN2803 to control electrified turn outs. 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 two pins labeled C- and C+ for the coil voltage (12-18V DC) for your turn outs. There are two additonal C+ connections for the common wire and ports 1 to 8 can be used to control each coil of a turn out. Therefore a total of 4 turn outs can be controlled with one module.

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 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.
