This listing is for the full Robo-Tank DIY Aquarium Controller without the AC Power Bar and some heavier parts which can easily be sourced locally. This will bring the shipping size and weight down dramatically for international users.

This kit is straightforward for assembly however some minor soldering is required, there's 4 wires + 2 temperature sensors in total to be done. You also need to program the Arduino and plug into the PCB's.

One the right side of the page there's an option to select if you don't want any soldering. With this I will solder the wires and include some 12" Dupont cables that will fit the sensor pins and allow you to add the screw terminal connectors. 

To assemble the controller you only need to mount the circuit board, add a DC power socket and an external LED power indicator, all hardware is included.

To assemble the display you need to plug the display in the PCB, mount them in the case and mount the photocell on the side of the case, all hardware is included.

To assemble the pH addon you only need to mount the circuit in the case.

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 to controller and Ethernet connection

This kit includes the following.

  • Robo-Tank Controller PCB (assembled and tested)
  • Robo-Tank Display PCB (assembled and tested)
  • Robo-Tank pH PCB (assembled and tested)
  • 7" Full Color Touch Display (fully tested)
  • 2 - Arduino Due's 
  • Mini w5100 Ethernet Module
