Case-free board-level gateway for OEM equipment integration
Overview
The Teltonika Oxa is Teltonika Networks' first embedded industrial IoT gateway designed specifically for OEMs and device manufacturers. Rather than bolting an enclosed DIN-rail router onto a machine, Oxa is a case-free board-level device that embeds inside the host equipment, adding LTE cellular connectivity without the cost and lead time of developing a custom module-level design.
At its core is a 1.3 GHz ARM Cortex-A7 processor with 128 MB of DDR2 RAM and 512 MB of SPI flash, running Teltonika RutOS — the same OpenWrt-based Linux environment used across the RUT router and TRB gateway families. That gives integrators full Linux headroom rather than a fixed-function modem firmware, with industrial protocol support spanning Modbus TCP, OPC UA, DNP3, BACnet/IP, DLMS/COSEM and MQTT.
Networking combines LTE Cat 4 cellular, a Gigabit Ethernet port, an SMA antenna connector, a Mini SIM slot and a micro-USB virtual network interface, plus one digital input and one digital output for simple event and control integration. The wide 9-30 VDC input and -40 C to +75 C operating range suit cabinet, pole and machine-mounted deployments.
Key Benefits
Board-level OEM integration — embed cellular and RutOS directly into equipment instead of adding an enclosed gateway. Full Linux headroom with industrial protocols (Modbus TCP, OPC UA, DNP3, BACnet/IP, DLMS/COSEM) plus OpenVPN, IPsec, WireGuard and ZeroTier VPN support, and centralized remote management via Teltonika RMS. Compact and rugged at 70 x 18.2 x 67.7 mm and 36 g with a -40 C to +75 C range and 9-30 VDC input.
Applications
OEM equipment cellular retrofits, industrial machine connectivity, remote monitoring and telemetry, smart metering and DLMS/COSEM deployments, building automation (BACnet/IP), and distributed industrial IoT installations where a DIN-rail router will not fit or is too costly.
