MASTER CubeSat OBC
Modular and expandable On-Board Computer
MASTER is 2NDSpace’s high-performance On-Board Computer for CubeSat missions from 1U to 16U, providing reliable platform control and in-orbit data handling. It is based on a dual-core processing architecture with integrated memory and data storage, multiple communication interfaces, OTA (Over-The-Air) update support, and FreeRTOS compatibility.
MASTER can be expanded with multiple add-on modules for payload data handling and platform subsystem controls.
