About
MASTER is 2NDSpace’s CubeSat On-Board Computer, built around a dual core processor for multi-operation handling: a Cortex M7 running at 480MHz paired with a Cortex M4 at 240MHz. It supports over-the-air (OTA) updates and is built on a FreeRTOS-compatible architecture. MASTER provides 13 communication interfaces including CAN, RS422, RS485, UART, USART, I2C and SPI, along with 8 GPIO and 6 ADC inputs. Onboard storage includes 2x SD storage memory slots, 64 Mb synchronous DRAM and 32-Mbit SPI serial flash memory. The board also integrates a 6-axis IMU and a temperature sensor, making it a compact and complete command-and-data-handling solution for CubeSat missions. A full datasheet (rev 3.0) is available for download.
