Introducing the Teltonika CALYX — Cellular Raspberry Pi HAT for Industrial IoT
Teltonika Networks has taken its industrial DNA and applied it to one of the world’s most popular edge platforms — the Raspberry Pi. The result is CALYX, a family of cellular HATs that bring enterprise-grade 4G, 5G and 5G RedCap connectivity to Pi-based systems.
Available now in three models — EBD021 (4G LTE), EBD050 (5G), and EBD070 (5G RedCap)
Built on Teltonika reliability
Each CALYX HAT is powered by an embedded cellular modem derived directly from Teltonika’s industrial router range. That means genuine long-term reliability and full compliance with industrial EMC and safety standards.
CALYX boards connect to the Raspberry Pi through the 40-pin header, draw regulated 5 V DC power and support USB data transfer for integration with custom Linux applications. The result is a compact but rugged platform suited to telemetry, edge computing, and mobile infrastructure.
CALYX EBD021 – 4G LTE Cat 4 Pi HAT
The Teltonika EBD021 delivers dependable 4G LTE Cat 4 connectivity (up to 75 Mbps DL / 50 Mbps UL) with 3G and 2G fallback. It’s the ideal entry point for field gateways and low-to-medium bandwidth IoT nodes where resilience and coverage matter most.
Typical uses
- CCTV and ANPR camera backhaul
- Environmental and agricultural monitoring
- Smart-cabinet telemetry / POS fail-over
- SCADA and remote PLC nodes
With a compact footprint (56 × 23 × 95 mm), dual SMA antenna ports and an operating range from −40 °C to +75 °C, the EBD021 is the simplest way to industrialise your Raspberry Pi project.
CALYX EBD050 – 5G Pi HAT
For higher throughput and low-latency applications, the Teltonika EBD050 integrates a 5G NR (Sub-6 GHz) modem (3GPP Release 16) offering up to 2.4 Gbps downlink and 900 Mbps uplink, with LTE Cat 19 fallback. It’s perfect for engineers pushing edge AI, video analytics or real-time process control.
Applications
- Multi-camera CCTV sites
- Smart-factory automation
- Event and retail WAN fail-over
- Portable 5G edge compute
Four SMA connectors provide true 4×4 MIMO performance.
CALYX EBD070 – 5G RedCap Pi HAT
The Teltonika EBD070 introduces 5G RedCap (Reduced Capability) — the middle ground between LTE Cat 4 and full 5G. Designed for power-sensitive industrial IoT, it provides up to 223 Mbps DL / 123 Mbps UL and dramatically lower energy use.
Ideal for
- Smart-city sensors and utility nodes
- Fleet and transport tracking
- Remote monitoring / telemetry
- Energy and environmental systems
RedCap delivers the latency and efficiency benefits of 5G without the cost and complexity of full eMBB hardware — a smart, future-ready balance for industrial applications.
Common features across the Teltonika CALYX Pi Hat range
- Industrial temperature rating (−40 °C to +75 °C)
- Nano SIM slot (+ optional eSIM support)
- Status LEDs for power and network state
- USB-C data/power interface
- 40-pin GPIO header integration
- Mounting kit included
IoT SIM cards for CALYX
Every Teltonika CALYX module needs the right data backbone. Standard consumer SIMs simply don’t deliver the reliability or control demanded by field devices.
Millbeck Communications — a Teltonika Diamond Partner — supplies IoT SIM cards built for industrial connectivity:
- Multi-network roaming SIMs for maximum uptime
- Private APN SIMs for secure fixed-IP access
- Dynamic IP SIMs for outbound cloud telemetry
- eSIM (eUICC) profiles for remote operator switching
For more details, see our IoT SIM page for contact the Millbeck team to build the right bundle of hardware, SIMs and antennas for your project.
Why CALYX matters
By combining Raspberry Pi flexibility with Teltonika industrial hardware, CALYX enables rapid development and reliable deployment using the same platform. Prototypes can become production units overnight, reducing integration time and cost.
Whether you’re designing CCTV nodes, EV charger controllers, or environmental sensors, CALYX gives you a professional-grade cellular gateway with a minimal footprint.
