Addon cards can significantly improve the interface capabilities of a CubeSat onboard computer by expanding its functionality, enhancing data acquisition, and supporting mission-specific hardware. Here’s how they help:
- Serial interface support: Multi-UART or CAN bus card
- Sensor integration: IMU or magnetometer daughtercard
- Image processing: FPGA or GPU compute module
- Storage: SD card expansion or flash memory module
- Communications: S-band/UHF radio transceiver module
- Power management: MPPT or battery monitoring addon
