Embedded Cellular Raspberry Pi HAT+

Introducing Teltonika CALYX — the new industrial-grade cellular HAT+ that transforms your Raspberry Pi 4/5 into a reliable, field-ready IoT gateway.

Whether you’re building remote sensors, Edge-AI devices, digital-signage controllers or telemetry nodes, CALYX gives you connectivity and stability where Wi-Fi or Ethernet just won’t cut it

  • Seamless Raspberry Pi integration — CALYX mounts directly onto Pi 4 or Pi 5 via the 40-pin header or USB-C, preserving the Pi’s compact footprint and eliminating bulky USB dongles or messy setups
  • Flexible connectivity: 4G, 5G RedCap or full 5G — choose the variant that fits your project: 4G for widespread, cost-effective deployments; 5G RedCap for efficient mid-range IoT; or full 5G for high-bandwidth, low-latency applications
  • Industrial-grade resilience — built for real-world deployments, CALYX operates in harsh conditions from –40 °C to +75 °C, making it ideal for factory floors, remote sites or outdoor kiosks
  • Advanced control & audio capabilities — GPIO modem control enables remote reboot/power-cycle or wake-up, ensuring reliable 24/7 uptime even in critical or inaccessible installations. It also supports PCM audio — useful for voice/SMS gateways or audio-enabled IoT solutions.
  • Rugged, production-ready IoT gateway — CALYX turns a standard Pi from a hobbyist board into an industrial-ready IoT platform: perfect for telemetry, remote monitoring, SCADA, Smart City, digital-signage, EV-charger control and more.
