DETAILS ON MODULAR EMBEDDED

Of the shelf hardware Special hardware Operating system Deep Embedded

ARMV7-A as the 32bit platform

ARMV8-A as the 64bit platform (A57)

Recommended

• Gbit LAN, USB3

Often USB2 and 100Mbit LAN only

(Raspberry Pi)

Gbit LAN often connected via USB

resulting in low network performance
