  • Each wire length will vary due to where you place the sensors and other electronics.

Procedure - Terminal Header[edit | edit source]

This procedure is the assembly process of the I2C and 5V/GND rail used for all of the sensors on the Growbot.
  1. Begin by cutting the terminal strip to size.
  2. OSHE Growbot Header WireStrip.jpg
    Strip enough wire to cover across the terminal strip.
  3. OSHE Growbot Header TinnedWire.jpg
    Tin the wire and terminal strip pins.
  4. Place the terminal strip on a breadboard.
  5. OSHE Growbot Header Soldered.jpg
    Solder wires onto the strip.
  6. OSHE Growbot Header Glued.jpg
    Use hot glue to hold the strips together.
  7. Press strips into printed terminal holder.

Procedure - Wire Harness[edit | edit source]

The left side of each photo connects to the main sensor board. The right side either runs to Raspberry Pi or terminal block for I2C or 5V/GND.
  1. OSHE Growbot Harness Overall.jpg
    We will be creating seven-wire harnesses for the various sensors.
  2. OSHE Growbot Harness UART.jpg
    This harness is the UART connector for the Odrive to Raspberry Pi. The connector is ~200mm long. The Odrive side has two terminal headers. Raspberry Pi side has a 1x2p DuPont connector.
  3. OSHE Growbot Harness ADC.jpg
    This harness is for the ADC to power and I2C header. The connector is ~75mm long. ADC side has a 1x4p DuPont connector. The power/I2C header side has two a 1x2p DuPont connectors.
  4. OSHE Growbot Harness 9dof.jpg
    This harness is for the 9dof sensor to power and I2C header. The connector is ~185mm long. The 9dof side has a 1x5p DuPont connector. The power/I2C header side has two 1x2p DuPont connectors.
  5. OSHE Growbot Harness MotorDriver.jpg
    This harness is for the motor driver to Raspberry Pi. The connector is ~200mm long. The motor driver side has a 1x5p DuPont connector. The Raspberry Pi header side has a 2x3p DuPont connectors.
    1. NOTE: The second side will vary with how you program the driver.
  6. OSHE Growbot Harness MotorPwr.jpg
    This harness is for the motor driver to power. The connector is ~120mm long. The motor driver side has a 1x2p DuPont connector. The power header side has a 1x2p DuPont connector.
  7. OSHE Growbot Harness soil.jpg
    This harness is for the soil sensor to power and I2C header. The connector is ~220mm long. Soil sensor side has a 1x4p DuPont connector. The power/I2C header side has two 1x2p DuPont connectors.
  8. OSHE Growbot Harness WireFollowing.jpg
    This harness is for the wire following sensor to power header and ADC. The connector is ~155mm long. Wire following sensor side has a 1x4p DuPont connector. The power header and ADC side has two 1x2p DuPont connectors.
