Qty.	Component
1	Pre-assembled Electronics Box
6	M5 x 10mm Screws
6	M5 Tee Nuts
2	Cable Guides

Step 1: Attach the electronics box to the gantry

Attach the pre-assembled electronics box to the middle slot on the outside of the left gantry column using two M5 x 10mm screws and tee nuts. The screws should be placed in the middle holes on the top and bottom mounting flanges of the electronics box. The top flange of the box should be butted against the bottom edge of the gantry corner bracket.

Step 2: Attach the cable guides

Attach both cable guides to the back side of the left gantry column using M5 x 10mm screws and tee nuts as shown. Adjust the guides so they secure the motor and encoder cables, UTM cable, LED lights cable, vacuum pump cable, camera cable, and the water tube. Ensure the water tube is not compressed.

Note: the cables and tubing are not shown in this image.

Step 3: Connect the peripherals

• Connect the LED lights to the Farmduino peripheral connector labelled LIGHTING (the top right connector on Farmduino). The connector will only fit in one direction.
• Connect the solenoid valve cable (with blue heat shrink) to the Farmduino peripheral connector labelled WATER (directly underneath the lighting connector). The connector will only fit in one direction.
• Connect the vacuum pump cable (with gray heat shrink) to the Farmduino peripheral connector labelled VACUUM (directly underneath the water connector). The connector will only fit in one direction.

The peripheral connectors are highlighted in orange

Step 4: Plug in the stepper motors and rotary encoders

Plug in the motor and encoder cables to the Farmduino. Each cable is labelled with a white sleeve, which corresponds to the connectors on the Farmduino. From left to right, the connectors on Farmduino are X1, X2, Y, and Z. Each connector can only be inserted in one direction, and has a locking tab to prevent it from falling out.

Step 5: Plug in the camera

Plug in the camera to the USB adapter cable.

The USB adapter cable is highlighted in orange

Step 6: Plug in the UTM cable

Plug in the UTM cable to the Farmduino. The connector will only fit in one direction.

The UTM connector is highlighted in orange

Step 7: Plug the power supply into the Farmduino

Connect the red 2-pin power supply connector to the Farmduino’s power input. The connector will only fit in one direction.

Step 8: Install the heat sinks on the stepper drivers.

The heat sinks allow for better heat transfer to the air. They are a set of small fins that effectively increase the surface area and allow for better heat rejection. Install the heat sinks in the vertical orientation to take advantage of natural convection.

Place the heat sinks squarely and directly on the stepper driver chip in the vertical orientation as shown in the graphic above. The heat sink components will allow the stepper driver chips to remain cool enough to operate in hot environments.

Step 9: Insert the supergland

Insert one half of the supergland into the slot in the bottom of the electronics box. The left-most hole in the supergland should be small (it is for the camera) while the right-most hole should be medium-sized (it is for the power supply).

Organize and position the cables into the supergland. From left to right, the cables should be: camera, UTM, motors, encoders, peripherals, power supply.

Once the cables are all inserted into the first supergland half, gently insert the second half of the supergland into the slot in the electronics box. Ensure that the flanges of both supergland halves are on either side of the electronics box wall.

Step 10: Install FarmBot OS onto the microSD card

Follow these instructions on the software documentation hub to install FarmBot OS onto the microSD card.

Step 11: Mount the power supply

Mount the power supply to your supporting infrastructure using four 25mm wood screws. The power supply is IP67 rated, so it can withstand rain and the elements.

Step 12: Plug in the power supply

Connect the waterproof screw-together 2-pin connector of the power supply cable into the power supply output.

Before plugging the power supply into an outlet or an extension cord, please read the precaution below.

If everything looks good, and you understand the precautions needed around powered electronics, go ahead and plug the power supply into a GFCI outlet.

If an appropriate outlet is not close enough to plug in directly, use an extension cord and the provided green outdoor electrical connection protector.
