A complete 5G router on a 74 × 42 mm board — cellular engine, routing firmware and interfaces already assembled and tested. Your product gets an integrated connectivity layer without a second design team.
Supply under your own brand, from 1 unit. Printed label samples the same day. See OEM & private label options →
Overview
The M400-E is a complete router on a board: 5G Sub-6 cellular engine, routing firmware in flash, two gigabit Ethernet ports, dual serial and the antenna connectors, all assembled and tested. An equipment maker who needs the machine online adds a 74 × 42 mm board instead of starting a modem integration from a chipset datasheet.
The format is board-to-board. Your host board supplies the DC 12 V rail and talks to the module over Ethernet and serial; the cellular and antenna side is already handled, including the four IPEX-4 connectors and the RF layout. That is the part of a modem design that most often needs a second iteration, and it is the part you do not have to do.
Configuration, branding and final inspection stay with our own team. Firmware default settings, boot behaviour and enclosure labelling can be set for your product line, and private label runs from a single unit — so the first prototype can already carry your brand.
Full routing firmware on board — NAT, VPN, DHCP and the web interface come with the module.
Your host board gets a routed gigabit interface without adding a switch or a second PHY design.
RS-232 and RS-485 on the same module, so the equipment controller and the telemetry path share one board.
Private label from 1 unit, with firmware default settings configured for your product line.

Integration support
A module sale is an engineering relationship. These three things come with every integration, not as an extra charge.
Pin-out, power sequencing, antenna placement notes and the host-board example we use ourselves.
Your integration questions go to the module team — the same engineers who set the firmware defaults.
Boot behaviour, APN defaults, interface naming and label strings set for your product line before shipment.
Applications
Products our distributors and OEM customers have built around this module family.
A 5G module inside a public-address and audio terminal, forwarding stream and status over the cellular link.
5G module on a UAV payload board, giving the ground station a routed link instead of a raw modem.
The module as the cellular core of a customer-branded gateway, with their own application board on top.
Payment and telemetry traffic over 5G, integrated into the machine controller board.
Gigabit Ethernet from the module straight into the appliance, no additional PHY on the host board.
One module across a product range, with firmware defaults and labels matched per model.
Downloads
The datasheet opens straight away — no form, no account. Compliance documents and integration drawings are sent on request; the user manual and firmware are released after a short form, so we can keep track of which hardware revision you are running.
Band sets per platform and region, pin-out, electrical characteristics and integration notes.
Outline drawing, connector positions and the recommended host-board footprint — released to integration partners.
Current firmware revision, default settings and upgrade procedure, released after a short form.
