The OBC-SM-DT-SAMV71 from SPACEMANIC is a Satellite On-Board Computer (OBC) that uses a 32-bit Cortex-M7 microcontroller and Spacemanic motherboard. This OBC has a flash storage capacity of 128 MB and a 384Kbytes multi-port SRAM. It comes with a FreeRTOS-based operating system and the software is compatible with a variety of commercial RTOS. The OBC requires a power supply of 3.3-5 V and has an average power consumption of 100 mW. It features an onboard temperature sensor, gyro sensor, magnetometer, and accelerometer sensor. The OBC supports I2C, UART, CAN, SPI, USB, PWM and Ethernet RMII interfaces along with QPI for external additional memory. It has a mass of 0.25 Kg and measures 65 x 40 mm. The OBC is suitable for nanosatellite C&DH, TT&C, mass storage, and ADCS.
