Teltonika EBD021 Calyx 4G Embedded Cellular Raspberry Pi HAT+ (NO PSU)
Teltonika EBD021 Calyx 4G Embedded Cellular Raspberry Pi HAT+ (No PSU)
The Teltonika EBD021 Calyx is an industrial-grade 4G LTE Embedded Cellular Raspberry Pi HAT+ designed to provide reliable cellular connectivity for Raspberry Pi 4 and Raspberry Pi 5 platforms. Purpose-built for Industrial IoT (IIoT), edge computing, smart city, energy, utilities, and automation applications, the EBD021 delivers seamless LTE Cat 4 connectivity in a compact HAT+ form factor that mounts directly onto the Raspberry Pi GPIO interface. With integrated modem control, USB Type-C connectivity, Nano SIM support, and industrial-grade durability, the Calyx simplifies the deployment of connected embedded systems without requiring external gateways.
Designed for developers, system integrators, OEMs, and industrial solution providers, the EBD021 combines LTE Cat 4 cellular networking with GPIO modem management, PCM audio support, and a rugged operating temperature range of -40°C to +75°C. The embedded design enables direct control of modem power, reset, and wake functions through Raspberry Pi GPIO pins, while dual SMA antenna connectors ensure dependable wireless performance. This version is supplied without a power supply (No PSU), making it ideal for custom embedded systems where power is already integrated into the deployment.
