This is the controller fully assembled, simply plug in your Raspberry Pi and power up the controller with a 12v-24v DC power supply and your set.

We recommend the Raspberry Pi Zero 2 W or Pi 3 B+, the Pi 4 is ok but overkill and does run on the hot side. If you follow the links below and scroll 3/4 down the page you can find a Pi dealer in your location.

Although this is plug and play you still need to load reef-pi on the Raspberry Pi and plug it into the controller. The controller board will be mounted in the case, you just need to remove the lid and the Raspberry Pi plugs in. Here's a manual showing how to do that and one to setup the Raspberry Pi.

Installing Raspberry Pi in Controller

Setting up Raspberry Pi and Install reef-pi

The controller has a fully isolated pH circuit built in, simply plug in any pH probe with a BNC connector and you're ready to accurately monitor your pH.

Package Includes

• Controller installed in 3D printed case with faceplate
• 5, 2-3 pin pluggable screw terminal connectors
• CR1220 Battery Installed (Canada and USA only) International orders need to supply your own.

Parts required to power up and run controller - see options on right side

• Raspberry Pi Zero W, Pi Zero 2 W, Pi 3 or Pi 4 - EXAMPLE
• Recommend microSD card - EXAMPLE
• 12v-24v DC power adapter to power up the controller, between 1-5 Amps depending on the DC equipment you connect - EXAMPLE
• If you want to monitor pH you need a probe - EXAMPE

3D Printed Case

The controller comes in a 3D printed case, choose your choice of color on the right side and select which Raspberry Pi you'll be using as the case is custom to it. There many be small defects due to 3D printing but any will be minor and only have a visual effect.

Controller Details

Here are the main features of the controller.

• Isolated pH circuit for accurate and stable readings
• 2 independent DS18B20 1-wire temperature ports
• Automatic fish feeder port
• I2C Port for expansions
