 The main features are:
 
-- Safe 8-32V power input, enabling use in both 12V and 24V systems without
-  external voltage conversion. The inputs are protected to withstand different
-  power surges commonly present in the vessel's electrical network.
-- Power management using a 2.7V 60F supercapacitor that provides so-called
-  last gasp
-  energy for shutting down the device in a controlled fashion after the
-  system power is cut. The amount of time the supercap can provide power
-  depends on the SBC power consumption but
-  a 60F supercapacitor can power a Raspberry Pi 4 for 40 seconds which is
-  more than enough for the operating system to safely shut down itself.
-- Peak power management: The same supercapacitor circuitry is able to provide
-  peak current for power-hungry devices such as the Raspberry Pi 4B+, allowing
-  those devices to be powered using current-limited subcircuits such as the
-  NMEA2000 bus power wires.
-- Protection circuitry: The board is protected against noisy 12-24V voltages
-  commonly present on marine vessels or vehicles.
-- An optocoupled CAN bus controller, allowing for NMEA 2000 compliant 
-  connectivity to boat instrument network.
-- A battery-powered real-time clock circuit, allowing for the device to
-  keep time even in absence of GPS or internet connection.
-- ATtiny1614 microcontroller that controls the board communicates with
-  the computer using I2C and has pins and memory available for custom
-  functionality.
