QUICKSILVER firmware
Open-source flight controller firmware for FPV drones with sane defaults and OSD configuration.
What is QUICKSILVER firmware?
QUICKSILVER is an open-source flight controller firmware for FPV drones, providing stable and responsive flight performance. It supports various STM32 and AT32 processors and focuses on ease of use with sensible defaults and accessible configuration via OSD. The firmware is designed to simplify setup and enhance the flying experience for drone enthusiasts.
FPV drone builders, hobbyists, and developers looking for a reliable and easy-to-configure flight controller firmware for custom or commercial drone projects.
Developers choose QUICKSILVER for its outstanding level-mode performance, straightforward configuration, and strong community support. Its cross-platform configurator and OSD-based adjustments make it accessible and user-friendly compared to more complex alternatives.
Overview
Flight Controller Firmware
Use Cases
Best For
- Building custom FPV drones with STM32 or AT32 flight controllers
- Drone enthusiasts seeking stable and responsive flight performance
- Hobbyists who prefer easy configuration via OSD and desktop apps
- Developers experimenting with drone firmware using PlatformIO
- Projects requiring reliable level-mode (angle/horizon) flight characteristics
- Open-source drone firmware development and customization
Not Ideal For
- High-performance racing drones requiring extensive low-level PID tuning and custom filtering
- Commercial or research drones needing integrated GPS navigation and autonomous flight modes
- Projects using flight controllers with processors outside the supported STM32/AT32 range
Pros & Cons
Pros
Offers dedicated apps for Windows, macOS, Linux, and a web version, making configuration accessible from any device, as highlighted in the README.
Key settings can be adjusted via the On-Screen Display during flight, enabling real-time tuning without a computer connection, which is a listed feature.
Pre-configured settings work well out of the box, reducing setup time and complexity for new users, as emphasized in the project philosophy.
Simple save and restore functions for configuration parameters facilitate backup and sharing of setups, making it user-friendly.
Cons
Only compatible with specific STM32 and AT32 processors, excluding other common flight controller chips, which may restrict hardware options.
Focuses on simplicity and level-mode performance, lacking built-in support for GPS navigation or autonomous modes compared to alternatives.
Documentation is hosted on a separate site (docs.bosshobby.com), which might be less integrated or slower to update than embedded documentation.
