Introducing RockBLOCK 9604
The RockBLOCK 9604 makes it easy to use Short Burst Data (SBD), Cellular LTE-M and GNSS services with your project. Providing highly-reliable 2-way messaging with short end-to-end transmission times from anywhere on Earth.
RockBLOCK 9604 - fully featured version.
The PCB assembly hosts an Iridium 9604 transceiver module. Simplifies the power requirements, and provides a serial interface to your project (USB-C and TTL). RF considerations are taken care of by RockBLOCK 9604's integrated patch antenna, or SMA connector for an external Iridium-9604 qualified antenna.
RockBLOCK 9604 Mini - small and easy to integrate.
The RockBLOCK 9604 Mini is designed for direct integration. Perfect for customers who wish to take advantage of the 9604 feature set using a form factor that can be easily hand soldered onto a PCB assembly. The PCB outline is only 35 x 37mm and already integrates robust SMA connectors, a SIM card slot and LED indication. Power and serial options are available via x2 6 way 0.1" pin headers.
