LS1043S Router Board

The LS1043-S Multi WAN router provides a powerful and flexible platform for branch office connectivity, deep packet inspection firewalls and redundant connectivity.

Equipped with the NXP LS1043 (Quadcore) system on chip, containing Cortex-A53 processing units, multiple Ethernet, USB3.0 and PCI Express, the LS1043S platform is capable of handling up to 5Gbps of simultaneous traffic. Interface options include A/VDSL, Gigabit Ethernet, LTE, 802.11n and 802.11ac WiFi. 4GB of DDR4 memory provides ample headroom for advanced networking and virtualization applications, with other RAM sizes available on request.

The LS1043S supports OpenWrt and other ARM64 Linux distributions. Mainline Linux kernels are supported from Linux 4.15 onwards, using fully standard kernel interfaces.

Storage options include a M.2 Key M slot (SATA) for SSD storage, as well as MMC/SD and 512MB of NAND flash.

The LS1043S comes in both DC plug and internal Molex variants to suit desktop and rackmount applications.

A DSL plug in card is in development.
