README
README.mdCAS Interface Board 2026
Control Actuation System (CAS) Interface Board for the UTS Rocketry avionics stack.
This board provides closed-loop control for the airbrake and parafoil control systems, along with sensor interfaces and onboard data logging. The design is based on the STM32F405RGT6 microcontroller and integrates inertial sensing, actuator control, and non-volatile storage.
The CAS board is intended to operate as part of the UTS Rocketry flight avionics architecture.
Overview
The CAS Interface Board is responsible for:
- Airbrake deployment control
- Roll stabilisation control
- Sensor acquisition
- Data logging
- Actuator interfacing
Closed-loop control is performed onboard using IMU, barometric sensor, and GPS measurements.

Questions
How big is the CAN Interface Board PCB?
It measures 50 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CAN Interface Board use?
70 parts, built around the STM32F405RGT6, SN65HVD230D, LSM6DS3TR-C and SRV05-4.TCT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CAN Interface Board KiCad files?
From the UTS-Rocketry/KESTREL-Control-Board2026 repository on GitHub, at the commit this page was made from: the board is Schematics/CAN-Interface-Board.kicad_pcb and its schematic Schematics/Barometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CAN Interface Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask UTS-Rocketry before reusing the design.
