The Linux Automation GmbH FairyTux2 is a small Linux device based on an Octavo Systems OSD32MP153c SiP, that occupies just two slots on a DIN rail. The device contains an eMMC for storage, a gigabit Ethernet connection, a CAN bus and a RS485 transceiver. Add support for the lxa-fairytux2 generation 1 and 2 boards based on the STM32MP153c.
