The first-generation Raspberry Pi 3 supports all versions of NEMS Linux. Raspberry Pi 3 Model B+ requires NEMS 1.3.1 or higher.
The Raspberry Pi 3 is a quad-core SBC which NEMS Linux will automatically throttle between 600 MHz and 1.2 GHz depending on need. It has a low-speed SD card reader, USB 2.0, 10/100 Ethernet, 1 GB DDR2 RAM and 802.11n WiFi.
The Raspberry Pi 3 Model B+ supports speeds around 15-20% higher, with significantly faster Ethernet (Up to 330 Mb/sec).
In order to run NEMS Linux on the ODROID XU4 (or its “quiet” XU4Q model) you will need NEMS Linux 1.4 or higher. The ODROID XU4 is an octa-core SBC which NEMS Linux will automatically throttle between 1.0 GHz and 2.0 GHz depending on need. It has a UHS-I SD card reader, eMMC storage capability, USB 3.0, Gigabit Ethernet and 2 GB DDR3 RAM.
