Teltonika Calyx: Cellular Raspberry Pi HAT

The Calyx is a purpose-built industrial-grade cellular Raspberry Pi HAT+ that delivers stable, high-performance mobile connectivity to the Raspberry Pi 4 and 5.

For years, developers working with the tiny but mighty Raspberry Pi for commercial and industrial applications faced a compromise. Their projects often relied on bulky USB dongles or unstable M.2 extensions to get online. These options compromise the Pi's essential compact footprint and introduce unacceptable points of failure in mission-critical environments.

Besides, they were never engineered for the continuous operation and wide temperature extremes of the factory floor or the remote utility site. Calyx is here to change that.

Teltonika Calyx transforms the widely accessible single board computer into a professional, resilient IoT gateway, providing reliability and high integration for applications requiring real-time response.

Available in three variants – 4G Cat 4, 5G Redcap, and full-fledged 5G – CALYX provides cellular connection to your Raspberry Pi 4 or 5 wherever Wi-Fi or Ethernet are unavailable or unreliable.
