1 Overview
The SecureMesh Ready, Open Smart Device Interface Modules (OSDI) are Trilliant 2.4GHz RF modules which can be integrated into a
variety of third-party OEM products. These small and versatile modules include a microcontroller, memory, transceiver, power
management all on an LGA circuit board.
Based on IEEE 802.15.4 wireless communication standard and utilizing Trilliant’s robust SecureMesh networking protocol, the OSDI
modules deliver industry leading 2.4GHz networking solution. The modules are easy to integrate, provide low power consumption, long
range and many more features and functionalities.
The OSDI family of products are currently available in 2 base hardware models:
