Teltonika CALYX – Industrial Cellular Pi Hat Series
Bringing professional 4G / 5G / 5G RedCap connectivity to Raspberry Pi
The Teltonika CALYX range introduces true industrial-grade cellular connectivity to single-board computers.
The Calyx Raspberry Pi HAT does not run RutOS and does not natively support Teltonika RMS. Instead, it functions as a hardware expansion board for the Raspberry Pi, enabling 4G/5G cellular connectivity. The module operates similarly to our TRM-series modems and can be fully managed using standard AT commands, giving users direct control over cellular functions such as network registration, SIM management, and data connections.
Models:
- Teltonika Calyx EBD021 – 4G Pi Hat (CAT4)
- Teltonika Calyx EBD050 – 5G Pi Hat
- Teltonika Calyx EBD070 – 5G RedCap Pi Hat
Model Overview
Teltonika Calyx EBD021 – 4G (LTE Cat 4) Pi Hat
Reliable, cost-effective connectivity for mainstream IoT. LTE Cat 4 offers up to 150 Mbps downlink and 50 Mbps uplink, perfectly suited for telemetry, data logging, smart metering, and low-bandwidth camera systems. Stable, widely supported, and ideal for long-term M2M deployments.
Teltonika Calyx EBD050 – 5G Pi Hat
Full 5G NR capability for high-bandwidth and low-latency applications. Delivers multi-gigabit throughput where coverage allows, with seamless fallback to 4G LTE. Ideal for industrial automation, live video, or high-speed mobile WAN use. Designed for future-proof edge infrastructure.
Teltonika Calyx EBD070 – 5G RedCap Pi Hat
Built on emerging 5G RedCap (Reduced Capability) technology, combining the efficiency of LTE Cat 4 with 5G’s lower latency and improved network efficiency. Perfect for IoT and M2M devices that need dependable performance without the cost or power draw of full 5G NR. Future-ready for upcoming UK and EU RedCap rollouts.
Reliability and Security – The Teltonika Advantage
Teltonika Networks is known globally for industrial connectivity that simply doesn’t quit.
Every CALYX Pi Hat benefits from the same heritage found in their RUT-series routers and TRB modems:
- Rugged hardware engineered for 24/7 operation in demanding environments.
- Long lifecycle firmware support with consistent updates and security patches.
- Extensive testing for electromagnetic resilience, heat tolerance, and mechanical durability.
- Industrial security stack supporting encrypted VPN tunnels, firewall rules, and secure firmware signing.
When you deploy Teltonika hardware, you get more than connectivity – you get trust, traceability, and long-term support from a brand recognised in over 150 countries.
