SparkFun RockBLOCK 9704 – SMA/Patch Antenna: Global Iridium Satellite IoT Connectivity

The SparkFun RockBLOCK 9704 by Ground Control is a compact satellite communication breakout board built around the Iridium Certus 9704 IoT module, designed to provide truly global, low-data-rate connectivity. Featuring an integrated patch antenna and supercap charger for efficient low-power operation, it is an excellent solution for remote monitoring, asset tracking, maritime, environmental sensing, and off-grid IoT applications.

The RockBLOCK 9704 enables bi-directional messaging from 25 bytes up to 100 KB, with typical end-to-cloud latency under 10 seconds. Hardware interfaces include a 3.3V TTL UART, USB-C serial bridge for direct PC connection, and U.FL connector for GNSS passthrough, alongside support for SMA or built-in patch antenna configurations. Power-efficient operation makes it suitable for battery-powered and solar-backed deployments, with 1.4 W peak, 60 mW idle, and 5 mW sleep mode.

Key Features:

  • Global Iridium Satellite Connectivity: Works anywhere on Earth for bi-directional IoT messaging.

  • Data Throughput: Supports message sizes from 25 bytes to 100 KB.

  • Low Latency: Typical 10 s end-to-cloud delivery time.

  • Hardware Interfaces:

    • TTL 3.3V UART

    • USB-C serial bridge

    • U.FL connector for GNSS passthrough

    • SMA or integrated patch antenna.

  • Power Efficiency:

    • Operating voltage: 4.0–5.3 V DC (3.6–4.5 V battery).

    • Peak: 1.4 W, Idle: 60 mW, Sleep: 5 mW.

  • Cloudloop Data Integration:

    • Routes uplinks/downlinks to HTTPS or MQTT.

    • REST API + web dashboard for metadata, usage, and message status.

    • Flexible, pay-per-message billing for scalable deployments.

  • Compact Design: Ideal for remote, battery-sensitive IoT applications.
