Electronics

The Raspberry Pi pico control board will have to control the whole system.

Further components

Optional elements could be:

• further sensor boards such as:
  • a Li-Ion fuel gauge
  • an accelerometer and gyroscope module
  • a magnetometer
  • a GPS module
• a buzzer which works well around 4 kHz (C₈ = 4186 Hz)
• an amplifier and loudspeaker
• a monochrome OLED display

Laboratory equipment

The developers should have access to:

• tools (screwdrivers, pliers, ...)
• a multimeter
• a welding station
• micro-USB cables

For test purposes, the sensor boards can be assembled in a chain with stemma QT cables and controlled via USB with the help of a general-purpose serial bus adapter.
