This listing is for the Lightweight Robo-Tank DIY Aquarium Controller intermediate kit. The kit includes all the parts required and the end result will be like a plug and play kit however the AC Power Bar and some of the heavy pieces you can easily source locally have been removed to lower the shipping size and weight for international customers. 

The images show everything included and these are the parts you will need to get locally.

  • 3 - 5 Amp 12v DC Adapter to power up the controller
  • Standard Ethernet patch cable to connect display and controller
  • USB Male - USB Male patch cable to connect AC power bar and controller
  • AC Power Cord to power up AC Power Bar (same cable as a computer power cord)

This kit requires you to solder all the connectors, headers and other large components to the circuit boards making this kit more involved and for those of you who like to solder. All the actual components have been mounted and the PCB's have been powered up with basic power tests. I have a good success rate assembling PCB's so I feel confident if you can solder decent everything will work as expected.
