Product Description
OBC Command and Data Handling Board
Pre-engineered on-board computer that serves as the platform control computer for communications, payload control, and mission data management.
OBC provides 3 UART channels that can be assigned to VHF, UHF, and S-band communication modules. If they are not assigned to communication modules, users can repurpose them for other UART use. RS-485 / SPI / UART, SPI, CAN Bus, I2C, ADC, DAC, PWM, GPIO, and PPS are also available for subsystem and payload integration.
Supports hardware-accelerated cryptography, Secure Boot, differential firmware updates, and KVDB configuration data management.
OBC uses an SD card for payload data, event logs, system state, and telemetry around fault events.
The 90 x 96 mm board outline supports CubeSat stack configuration, harness routing, and third-party subsystem integration.
Define scheduling, mode transitions, ground command handling, and safe-mode logic as traceable platform operations.
Integrate UART, CAN Bus, SPI, I2C, GPIO, and PPS interfaces with ADCS, RF, EPS, and payload controllers.
Clear interface configuration, firmware update, data logging, and recovery functions shorten product adoption and system verification.
