Procedure - Terminal Header

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. Strip enough wire to cover across the terminal strip.
  3. Tin the wire and terminal strip pins.
  4. Place the terminal strip on a breadboard.
  5. Solder wires onto the strip.
  6. Use hot glue to hold the strips together.
  7. Press strips into printed terminal holder.
  8. Use hot glue to hold the wires into holder.
  9. Connector is now ready to be placed on electronics board
  10. Sample use of the header

Procedure - Wire Harness

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. We will be creating seven-wire harnesses for the various sensors.
  2. 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. 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. 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. 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. 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. 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. 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.
