Introduction

Before you commissioning the GNUBLIN Module-Rail-Relay you have to do some small soldering. First check, if all parts are correctly delivered.

  • Assembled and soldered PCB (SMD)
  • 6 x 2 pin terminals (green)
  • 2 x 14-pin sockets
  • 5 x Jumper
  • 4 x Relay G6D
  • 3 x 3 pin connector
  • 2 x 2 pin connector


Assembly

Now solder the parts in the following order: Frist the pin connectors followed by the 14-pin sockets. Then the relays. Last solder the pin terminals. you can connect two of them before you solder them. See the following picture:

Now the module is ready to use.

Inbetriebnahme

When starting up it is important that the I2C address and the pull-up resistors are set. However, the pull-up resistors must only be set if only one module is connected to the Gnublin. Or otherwise, at least to a module the I2C pull-up resistors must be set. The following figure shows the configuration for a module on the I2C connector.
