Sacramento-based Peregrine Developments has engineered a flight computer called the Randall FC using the Teensy 4.1.

Although rocket design has roots going back to thirteenth century China, modern model rockets have been a source of fascination for hobbyists and professionals alike since the 1950s. Early model rockets consisted of a simple 3″ motor built from a nozzle, case, propellant, delay charge, ejection charge and an end cap that amounted to a single-use engine. Today, model rockets can include complex assemblies such as onboard computer systems that allow users to steer and control rockets with great precision.

The system, which was designed for 74mm airframes, provides for the control of two 9g servo motors and two 4-amp pyro channels to control the flight of thrust vectoring-enabled model rockets. The system also has a system of onboard sensors for measuring orientation, acceleration, humidity, pressure, and temperature as well as four spare I/O connectors available for use. You can read more about the project and see the schematic and PCB layout on Google Docs.
