Quad-E4G is a universal platform offering wide possibilities thanks to multiple expansion slots. It provides extensive expansion options and decent performance. Three mini PCIe slots with both PCIe and USB buses, equipped with SIM slots, allow for assembling a wireless router with multiple WiFi or 4G modules.

An additional M.2 B-key slot makes it possible to create a high-performance 4G/5G access point with LTE Cat. 6+. Five Gigabit Ethernet interfaces with hardware offload support will serve many end devices without the need to worry about throughput.

OpenWrt support and USB-based system serial console make development extremely easy.
