Integrated on board MCU with pre-installed firmware offers additional useful features via I2C /GPIO interface (see examples in /opt)

Powered by CR2032 onboard MCU offers rough RTC clock and measuring external power even for off-time which is useful for investigation power source interrupts.

Watchdog functionality can be used for keeping the device in work state even if software issues make it unstable.

Each Mini PCI-E slot can be switched on / off separately via GPIO interface, so in any case of unstable behavior the developer can reboot modules easily by setting 0 / 1 on the corresponding GPIO line.

With all these features S42 DK is the perfect solution for creating reliable and powerful telecom-grade routers.

It is available in several configurations, starting from bare motherboard to fully equipped router in case with antennas and power source.
