It packs 4G LTE Cat 4, Gigabit Ethernet, the feature-rich RutOS and native Modbus, DNP3, OPC UA and BACnet support into a credit-card-sized, 36-gram board, so device manufacturers can skip custom module-level development entirely. Here's what it offers and who it's for.* For original equipment manufacturers, adding reliable cellular connectivity to a product has long meant choosing between two compromises. Custom module-level development offers a minimal footprint but demands serious engineering resources, complex certification and long development cycles. External boxed gateways are easier to deploy, yet often too bulky — and aesthetically mismatched — for sleek, integrated industrial designs. The new Teltonika Oxa is the middle ground. It's a compact, embedded IoT gateway engineered specifically for OEM and industrial integrations: a fully functional, pre-certified networking board that manufacturers embed directly into their host equipment, with no module-level engineering required. > **Note:** Source: the official Teltonika Networks launch announcement and the Oxa product page on teltonika-networks.com, plus the Oxa datasheet (v1.00) and 2026 product flyer. ## Big capability, credit-card footprint The Oxa is defined by its space efficiency — the board is roughly the size of a credit card, and four pre-drilled mounting holes (∅ 2.70 mm) let hardware architects secure it firmly inside a host chassis. Despite the size, it's rated for genuinely industrial environments: ![The Oxa is a board-level product: it embeds inside your equipment rather than bolting on beside it.](https://cdn.tech2have.com.au/blog/teltonika-oxa-embedded-iot-gateway/oxa-scene.jpg) ## Connectivity: LTE Cat 4, Gigabit Ethernet and a debug-friendly USB port Board-level doesn't mean bare-bones. The Oxa carries a versatile interface array: 4G LTE Cat 4 — up to 150 Mbps down / 50 Mbps up, with 3G and 2G fallback. An internal 2FF (Mini SIM) holder and a dedicated SMA connector for the mobile antenna. Gigabit Ethernet — a single 10/100/1000 Mbps port for high-speed local data transfer. Micro-USB “Virtual Network Interface” — local configuration and debugging without tying up the Ethernet port; a genuinely useful touch for engineers on the bench. Power + I/O on one connector — a 4-pin industrial DC socket (9–30 VDC) that also carries the hardware digital input and digital output (1x DI, 1x DO), simplifying wiring-harness design. 11 status LEDs — connection type, signal strength, LAN and power, positioned so enclosure designers can surface them through light pipes. > **Note:** Passive PoE caution: the Oxa can be powered through the LAN port via passive PoE (9–30 VDC), but this is Mode B only and is not compatible with IEEE 802.3af/at/bt power sources — connecting standards-based PoE may damage the hardware. Spec the power design accordingly. ## Industrial intelligence: RutOS and deep protocol support The Oxa runs RutOS — the same OpenWrt-based Linux environment as Teltonika's RUT routers and TRB gateways — on its 1.3 GHz Cortex-A7. That gives it far more headroom than a simple modem, and the software stack is built for industrial integration: Automation & energy: native Modbus (server/client), DNP3 (station/outstation), OPC UA and BACnet over TCP. Utilities: DLMS support for standard meter data exchange. Data handling: “Data to Server” parameter extraction, plus MQTT in both broker and publisher roles for modern IoT architectures. Custom applications: multiple programming languages, including Lua, C/C++, Java and Python; a Package Manager installs only the services your application actually needs. ## Security and fleet management Security is enterprise-grade out of the box: OpenVPN (27 encryption methods), IPsec (14 methods), WireGuard , ZeroTier and more for tunnelling, alongside a preconfigured firewall, VLAN separation and built-in prevention against DDoS, port scans and SSH attacks. For deployments at scale, the Oxa is fully compatible with the Teltonika Remote Management System (RMS) — centralised management, real-time monitoring and firmware-over-the-air updates across large device fleets. ## The OEM advantage For device manufacturers, the Oxa's pitch is strategic rather than just technical: Faster time-to-market — skip the module-level development and certification cycle with a ready-to-integrate gateway. Branded firmware — GPL customisation lets OEMs re-skin the WebUI (colours, logos and more) to match their own identity. Modular software — install only the packages the application requires. Seamless embedding — connectivity integrates into the host product, with no external boxes or bulky mounting. Teltonika's launch materials point at exactly the kind of deployment this suits: outdoor gates, turnstiles and barriers that need instant, secure access validation but sit far from wired infrastructure — an Oxa inside the controller delivers LTE connectivity without trenching, fibre or Ethernet runs. > **Note:** The Oxa is a brand-new release and isn’t in our range yet. Planning an OEM or industrial project around it? Contact us and we’ll arrange pricing and availability for you. ## Teltonika gateways you can order today If your project needs Teltonika-grade cellular connectivity now — or a DIN-rail / enclosed form factor rather than a board-level one — the TRB gateway family covers the same RutOS + RMS ecosystem in a rugged housing, from the ultra-small TRB160 to the 5G TRB501: New to the brand? Start with our Teltonika Networks range guide , or see the hardware applied in the field in our industrial automation and energy & utilities use-case round-ups. Raspberry Pi builders should look at the CALYX cellular Pi HATs — a similar embedded-connectivity idea in HAT form. **Q: What exactly is the Teltonika Oxa?** A: A compact embedded IoT gateway — a board-level product (order code EBG140AAAA00) that OEMs and industrial integrators build into their own equipment to add 4G LTE Cat 4 and Gigabit Ethernet connectivity, managed by Teltonika's RutOS. **Q: How is it different from a TRB-series gateway?** A: The TRB gateways are finished, enclosed devices you mount on a DIN rail or shelf. The Oxa is the board inside your product: it trades the housing for a 70 x 67.7 mm footprint, mounting holes and light-pipe-ready LEDs, so connectivity disappears into the host equipment. The software stack (RutOS, RMS, industrial protocols) is the same family. **Q: Does the Oxa come with a power supply?** A: No. The standard package (EBG140AAAA00) includes the gateway and a Quick Start Guide only — the PSU is specified separately to suit the integration, feeding the 4-pin 9–30 VDC socket or passive PoE (Mode B, 9–30 VDC). Note it is not compatible with IEEE 802.3af/at/bt PoE standards. **Q: Can I run my own software on it?** A: Yes. RutOS supports custom applications in Lua, C/C++, Java and Python, a Package Manager for optional services, and GPL customisation for fully branded OEM firmware. *(2 interactive product/price widget(s) omitted — see the web page for live pricing, or the product .md twins linked from https://level-floor.bnr.la/store/products.md.)* --- More articles: https://level-floor.bnr.la/blog/ · Store: https://level-floor.bnr.la/store/products.md · Index: https://level-floor.bnr.la/llms.txt
