DroneCore Jerboa

Release notes

rev.0

• First revision

Description

This single-board autopilot serves as the central UAV control unit, integrating both flight-control functionality and high-performance onboard computing on a single PCB.

It features an FMU based on an STM32H7 microcontroller responsible for real-time flight control and sensor data processing, together with an NVIDIA Orin module providing compute capability for advanced autonomy functions. Additionally, the board provides the main hardware interfaces for connecting other auxiliary modules within our ecosystem
