From the project

Embedded flight controller for the 2026 NURA competition.

Teensy 4.1 flight-computer firmware for the 2026 NURA rocket avionics stack.

The current codebase is built around a small cooperative scheduler, explicit state stores, hardware abstraction layers, and a lightweight LoRa telemetry/control protocol. It is still an active integration project: sensor acquisition, LoRa protocol work, mock telemetry, and ground-side receiver tests are in the repository, while flight rules, logging outputs, and final hardware validation are still being tightened.
