SIRMA™ consists of a low-power modular printed circuit board embedded between the two ends of a cable assembly. This assembly allows several functionalities such as data processing, data logging, and voltage regulation between a sensor and a platform such as a glider, AUV, or buoy. SIRMA™ turns any cable assembly from a passive device into a smart processing unit.
Basic Onboard Modules:
- 32-bit Microcontroller
- Step-up / Step-down Voltage Regulators
- Flash Memory Unit
- 16-bit Analog to Digital Converter (ADC)
