Add 4G/5G to Your Raspberry Pi: Teltonika CALYX Pi HATs
Teltonika's CALYX HAT range bolts industrial 4G or 5G cellular straight onto a Raspberry Pi — no bulky USB dongle or M.2 carrier. Tech2Have stocks the 4G, 5G and 5G RedCap HATs alongside the Raspberry Pi 5, so you can build a connected edge device out of the box. Here's what they do and where they shine.
The Raspberry Pi is a brilliant little edge computer — but on its own it has no mobile connectivity. Teltonika's CALYX embedded cellular HAT range fixes that: a low-profile board that mounts directly on the Pi's GPIO header and adds industrial 4G or 5G, with GPIO modem control and PCM audio. Tech2Have stocks the full range plus the Raspberry Pi 5 to run it.
The three CALYX HATs we stock
- EDB021 — 4G Cat 4 Pi HAT: reliable LTE for low-to-moderate data edge deployments. The cost-effective way to put a Pi online over cellular.
- EDB050 — 5G Pi HAT: full 5G throughput for data-intensive edge workloads — video, vision and high-rate telemetry.
- EDB070 — 5G RedCap Pi HAT: 5G RedCap (reduced-capability) balances 5G features with lower power and cost — ideal for always-on IoT sensors and monitors.
All three mount seamlessly on the Raspberry Pi 4 and 5, offering a space-saving, low-profile alternative to bulky M.2 modules or external USB cellular modems — and they're managed remotely through Teltonika's RMS platform.
Teltonika CALYX Pi HATs + Raspberry Pi 5 — in stock
Pair it with the Raspberry Pi 5
We stock the Raspberry Pi 5 (16 GB) — the quad-core BCM2712 board with the performance to do real work at the edge, not just relay data. Drop a CALYX HAT on top and you have a complete, cellular-connected edge computer ready for the field.
Real-world use case: IoT predictive maintenance
Predictive maintenance (PdM) cuts costly downtime in manufacturing. Running local machine learning on the Raspberry Pi means sensor data is analysed at the edge and only critical anomalies are sent upstream — drastically reducing data transmission. A 5G RedCap CALYX HAT gives that Pi resilient, future-proof connectivity for real-time alerts and remote monitoring, with GPIO control for advanced power management.
Real-world use case: digital-signage remote management
Interactive digital signage across a large shopping mall — directories, promotions, events — needs robust, reliable edge management across many displays. The CALYX HAT mounts on each Pi-driven sign and ensures future-proof connectivity for real-time content updates and remote management, so a whole estate of screens is controllable from one place.
