The Electronics directory contains the custom Arduino shield PCB that interfaces the Arduino Uno Rev3 with the motor driver, QB3 pressure regulators, solenoid valve, LCD screen, and the compute box’s power rails (see Wiring for the full pinout).

Arduino shield

Designed in KiCad. The project targets an Arduino Uno Rev3 shield footprint and breaks out the following interfaces referenced throughout the wiring guide:

  • Motor driver power and control (M_DRV_PWR, M_DRV_ARD, M_5V)
  • Solenoid valve output
  • 15 V actuator/regulator rails (M_15V, R_15V)
  • QB3 pressure regulator channels (Chamber, Actuator 1–3)
  • I²C breakout for the LCD display

To fabricate a board, download the contents of the v2_gerbers_8_23_2 folder (or the corresponding .zip) and submit it directly to your PCB manufacturer of choice.

To open and edit the design, clone the repository and open vine_robot_arduino_shield.kicad_pro in KiCad 7 or later — the custom footprint libraries in this folder are referenced by the project’s local fp-lib-table and will resolve automatically.

The shield is mounted alongside the Arduino Uno Rev3 in the compute box — see Assembly → Step 3 for installation and Wiring for the full connector pinout. CAD for the shield’s mechanical footprint and mounting is included in CAD → Compute Box.
