Global coverage from Iridium's satellite network

Our flagship RockBLOCK 9602 product utilises the Short Burst Data (SBD) element of the Iridium Satellite Network and is by far the most popular device in our SBD range. This small, robust device is used by hobbyists and scientists alike and is versatile in its uses – from meteorological sensing, through to preventing fires in remote locations

If space is at a premium in your unit, you may want to consider the RockBLOCK 9603 instead. This device has been designed especially for product developers and system integrators used to using smaller equipment for small enclosures.

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 satellite 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).
