Croí is the core flight-computer node in Ogma, the University of Limerick Aeronautics Society's modular avionics stack for high-powered rocketry.
- Coordinates flight state across the 500 kbit/s CAN bus.
- Samples an LSM6DSO32 IMU and MS5607 barometer.
- Records flight data to SPI NOR flash.
- Runs on an STM32F072 and can operate as the stack's central logger.

Rev 1 firmware and hardware bring-up continue on ogma/flight-hardening. Release-candidate firmware builds and software tests pass, but hardware-in-the-loop validation is still underway. Croí is not yet flight-proven.
Rev 1 PCB fabrication was sponsored through EasyEDA Education and manufactured by JLCPCB. The board was designed in KiCad and imported into EasyEDA Pro for the sponsorship and manufacturing workflow.
See the Ogma project write-up for the complete stack, bring-up work, and current status.
