hardware watchdog can also control the microSD switch matrix, swapping the boot
card in case the watchdog is triggered
✓ powerful and user-programmable 32 bit microcontroller (ATSAME54), with 1 MB
program memory and 256 KB RAM. The microcontroller is interconnected to the
Raspberry Pi via I2C, USB and CAN. It can also take direct low-level control of all serial
ports and digital as well as analog I/O
✓ integrated Serial Wire Debug (SWD) interface to the Iono Pi Max microcontroller,
allowing in-field firmware upgrades, but also development and debugging, directly from
the Raspberry Pi
✓ embedded Microchip ATECC608 secure element chip
✓ front-panel RGB LEDs for power supply and serial line activity, can also be directly
controlled by the Raspberry Pi
✓ on-board piezoelectric buzzer, for acoustic feedback
✓ front-panel push-button, connected to a GPIO pin
✓ power supply, serial and I/O connections on pluggable terminal blocks
✓ internal temperature sensors for system temperature monitoring
✓ internal fan, controlled by the microcontroller based on current load and internal
temperature
