Raspberry Pi Station - Hardware

Base Components

The following are required as base components:

  • Raspberry Pi 3 B+

  • heatsink for the Raspberry Pi SoC

  • industrial-grade Kingston SDCIT2 SD card

  • Sleepy Pi power management controller (Raspberry Pi hat extension)

  • short and "thick-enough" USB cables (lower resistance-induced losses)

  • a fan to maintain a constant cooling airflow within the enclosure

Leveraging the Sleepy Pi offers several benefits:

  • it is friendly to 12V or 24V power sources, e.g. solar panels

And allows:

  • to gracefully shut down and power on the Raspberry Pi

  • monitor supply voltage and drawn current (using the included Arduino)

  • control the fan power along the Raspberry Pi or enclosure temperature

  • lower global power consumption (e.g. along solar power sources)

Demonstrated use-case (FLARM receiver)

To enable the station as a FLARM receiver, one shall add:

AC-powered version

To power the entire apparatus from the facility (110-240V AC), one needs to add:

Which can be assembled as per given layout.

Solar-powered version

To use solar power - and make the station entirely independent - one needs to add:
