On Board Computer

The Data Patterns OBC is a flight qualified, robust computing platform ideal for Cube, Nano and Microsat missions. It contains a high performance dual core 32-bit power architecture PXS3020 micro controller with core operating frequency of up-to 180 MHz. The microcontroller can perform general functions of satellite like command handling, thermal & power management, payload data operations and attitude determination with control operations.

The module comes with a pluggable daughter board for additional features & flexibility. The daughter boards has I/O buffers, H bridge circuitry for torquers and connectors for ease of system integration.
