Teltonika EBD021
Teltonika Calyx EBD021 | 4G LTE Cat 4 Raspberry Pi HAT+ | Up to 150 Mbps downlink | 1x Nano-SIM | 2x SMA | GPIO | SPI/UART | For Raspberry Pi 4/5
Description
The CALYX EBD021 from Teltonika is an industrial embedded 4G/5G Raspberry Pi HAT+ that lets you directly expand your Raspberry Pi 4 or 5 with a reliable mobile data connection, ideal for IoT projects, gateways and edge computing applications.
This compact cellular HAT+ is specially designed to make embedded systems future-proof with stable 4G LTE, 5G or 5G RedCap connectivity, without major changes to the existing design.
Via the 40-pin GPIO header and USB-C, you connect the CALYX EBD021 seamlessly to the Raspberry Pi, with the data and power connection elegantly integrated into one professional, industrial form factor.
The module offers GPIO-controlled modem control (power, wake, reset) and supports management via AT commands, making integration into Linux-based IoT applications and custom software very easy.
In addition, the HAT+ supports PCM audio for clear, digital voice and audio applications, such as SMS/voice gateways and dedicated audio streams, and it is suitable for use in demanding environments with a temperature range of approximately ‑40 °C to +75 °C.
The modem is supplied as standard with an antenna, micro USB cable and 2 year warranty.
