Why choose EBD021?
Designed for developers and integrators building cellular-connected monitoring, automation and IoT systems around Raspberry Pi.
Bring mobile connectivity into your design
An integrated LTE Cat 4 modem adds a cellular network connection without relying on local Wi-Fi infrastructure. The EMEA variant supports widely used LTE bands, including B20 and B28.
Keep the assembly compact
The HAT+ form factor mounts directly onto Raspberry Pi 4 or 5. Supplied fasteners and a 40-pin header extender simplify mechanical integration.
Control the modem from your application
GPIO signals let your host switch, wake and reset the modem. This enables application-controlled recovery and power-state management when correctly implemented.
Build around documented interfaces
USB data connectivity, AT-command documentation and PCM audio support give developers a clear basis for integration. Two SMA connectors allow suitable external cellular antennas.
Plan the complete systemUse with a Raspberry Pi 4 or 5, compatible cellular antennas, a nano-SIM with a data plan and suitable power. Configure the host drivers and operator APN using the official guide.
Compact board-to-board integration
The 40-pin header and mounting points support a tidy Raspberry Pi assembly.
Accessible hardware interfaces
USB Type-C and GPIO connections support data transfer and host-controlled modem operation.
