Electronic components
Solder the pin strip (probably enclosed) to the microphone.
Result:
Solder the pin strip to the weight sensor on the side with 4 ports. On the side with 6 ports solder the wires of the straine gauge as follows:
- White -> A+
- Green -> A-
- Black -> E-
- Red -> E+
Attention: Depending on the actual straine gauge you use, maybe you have to use other connections. Our instructions are for the Adafruit straine gauge (1 kg).
- Connect camera to flex cable
- Put flex cable through hole in camera mount
- Fixate camera with M2 bolts in mount

Please have a look below for more detailed descriptions of the wiring of the individual components.
Connect the other side of the camera flex cable to the camera port on the Raspberry Pi.
Material: M5 bolt
Bolt the strain gauge to the bottom panel.
Material: Spax 3 x 25
Screw the perch to the strain gauge.
Result of steps 1 and 2:
Material: 4 x 10 cm dupont cable
Connect the weight sensor to the Raspberry Pi as follows:
- VCC -> Port 2 (5V)
- SCK -> Port 16 (GPIO 23)
- DT -> Port 11 (GPIO 17)
- GND -> Port 20 (GND)
Material: 3 x 20 cm dupont cable
Connect the sensor to the Raspberry Pi as follows:
- "+" -> Port 1 (3.3 V)
- Out -> Port 36 (GPIO 16)
- "-" -> Port 9 (GND)
Material: 6 x 20 cm dupont cable
Connect the sensor to the Raspberry Pi as follows:
- SEL -> Port 39 (GND)
- LRCL -> Port 35 (GPIO 19)
- OUT -> Port 38 (GPIO 20)
- CLK -> Port 12 (GPIO 18)
- GND -> Port 30 (GND)
- 3V -> Port 17 (3,3 V)
