Flexible OEM Sensor Processing
Low power, high capability data acquisition & processing

TR-Blue is a low power and highly capable OEM data acquisition and signal processing system, specifically designed for long term and autonomous deployments. TR-Blue is modular, it consists of an extremely flexible processing engine with a field programmable gate array (FPGA) and a tightly integrated ARM Cortex M4 processor for signal processing with expansion connectors capable of interfacing to almost any analog sensing system.

Turbulent Research provides analog signal conditioning and digitization expansion boards that mate directly with TR-Blue for applications in underwater acoustics.

TR-Blue has been optimized for low power consumption while still giving users access to serious processing horsepower and the flexibility to interface to just about any sensing system. Traditionally, researchers and scientists have had to use off the shelf single board computers or development kits to develop their new and innovative instruments, sacrificing optimized power consumption and system flexibility. TR-Blue is a platform designed to meet the real needs of these users without compromise.
