Utilizing the Short Burst Data (SBD) element of the Iridium Satellite Network, our flagship RockBLOCK 9602 product is one of the most versatile and popular items in our SPD range. From use cases involving meteorological sensing, through to preventing fires in remote locations, the RockBLOCK has a few tales to tell from hobbyists and scientists, through to global corporations.

If you’re looking for a smaller version of the RockBLOCK 9602 unit, then the RockBLOCK 9603 might suit you – designed primarily for product developers and system integrators where space inside an enclosure is at a premium.


How RockBLOCK Works

RockBLOCK takes its power from a standard 0.1″ pitch direct header connector, or alternatively via an FTDI to USB adaptor (to power/control from a USB port). If you’re using the PCB assembly version with a direct header, your host needs to supply a minimum of 100mA @ 5V.

At the heart of RockBLOCK is an Iridium 9602 modem. The RockBLOCK hosts the 9602 and provides it with an antenna, and its power supply requirements. It exposes the modem’s serial interface via a breakout connector over serial, or USB (via a USB/serial adaptor).
