UTM Cable
This 12-wire shielded cable connects the Farmduino to the UTM. It comes in two pieces, a Y-axis section and a Z-axis section that connect with a 90-degree screw-together waterproof connection at the cross-slide. It provides Ground, 5V, 24V, digital and analog I/O, with a pin mapping that can be configured at the Farmduino to support custom tools. It features connectors on both ends for easy connection to both the UTM and Farmduino, as well as a rubber shroud to protect the inside of the UTM from the elements.

Component tests
| Test | Description | Target | Tolerance |
|---|---|---|---|
| Length | Measure the length using a measuring tape. | See BOM spec | +/- 20mm |
| Diameter | Measure the diameter of the cable using digital calipers. | 7mm | +/- 0.5mm |
| Connectors | Connect a UTM to the Farmduino using the cable. | Connectors should fit as expected. | N/A |
| Continuity | Use a multimeter to check pinout and continuinty for each core through complete cable (Y and Z sections). | All cores are connected correctly | N/A |
| Cable | Inspect the cable’s spec. | 24AWG-12C shielded stranded copper cable | N/A |
| Shroud | Inspect the shroud and test fit on UTM. | Shroud should snugly fit on top of UTM | N/A |
| Color | Inspect the color of the cable. | Black | N/A |
| Function | Mount and dismount the Rotary Tool and Soil Sensor. Use a tools to verify cable function. | Tools work as expected | N/A |
