TELTONIKA CALYX 5G, EBD050, EMBEDDED CELLULAR RASPBERRY PI HAT+

5G and integration with Raspberry Pi

Teltonika Calyx 5G (EBD050) is an embedded cellular module in HAT+ format for Raspberry Pi 4 and 5, designed for projects requiring stable access to a mobile network. Direct mounting on the SBC reduces occupied space and simplifies integration in embedded systems [web:6][web:10].

Key advantages

• 5G Sub-6 GHz SA/NSA – provides high throughput in applications with heavy data transfer [web:7][web:11].
• 4x4 MIMO – increases connection performance for video transmission and real-time operation [web:7].
• USB 3.0 via USB-C – shortens data transfer time and simplifies connection to Raspberry Pi [web:2][web:7].
• 4 SMA connectors – offers convenient antenna selection and better operating conditions in the field [web:1][web:4].
• Modem control via GPIO – enables reset, wake-up and control from the Pi [web:5][web:10].
• Operating range -40 °C to +75 °C – suitable for industrial and outdoor installations [web:4][web:9].

Connectivity without compromise

The EBD050 version supports 5G NR SA/NSA and fallback to 4G LTE Cat 19, so it maintains a connection even where 5G coverage can be variable. In practice, this means more stable operation for monitoring, telemetry, IoT gateways and edge systems that cannot rely solely on Wi‑Fi or Ethernet [web:7][web:10].

Compact design

The enclosure, measuring 56 x 23.11 x 100.8 mm and weighing 57 g, makes it easy to create a compact build without unnecessary adapters and loose cables. Direct mounting on Raspberry Pi reduces the risk of accidental disconnection and tidies up the layout in end devices [web:2][web:4].

GPIO and PCM audio

The module uses 40-pin GPIO to control the modem, making automatic wake-up, restart and power management easier. PCM audio support provides low-latency digital audio transmission, useful in voice solutions, communication gateways and specialised integrations [web:5][web:10].

Practical applications

Teltonika Calyx 5G is ideal where quick deployment and remote device operation matter: in automation, monitoring, kiosks, telemetry systems and prototype projects. The included mounting kit, GPIO extension and USB-C to USB-A accessory make deployment easier without having to source additional components [web:4][web:10].

Bands and compatibility

The 5G / EBD050 variant supports a wide range of 5G NR, LTE and 3G bands, increasing the chances of operation across different networks and locations. This is important in multi-stage deployments, where the device must maintain connectivity despite changing operator infrastructure [web:1][web:7].

A solution for integrators

Calyx 5G combines a mobile modem, hardware control and a compact form in one module, making it easier to build Raspberry Pi-based devices. It is a practical base for integrators and developers who need industrial-grade cellular connectivity without complicating the project with additional interfaces [web:10][web:12].
