A flight controller, minus what you don’t need.

What does this do?
The flight controller is the drone's computer. This one runs Betaflight on an RP2354, a dual-core chip from the Raspberry Pi Pico family, reading a 6-axis IMU thousands of times per second and correcting all four motors to follow your commands. It records blackbox to a microSD card, draws OSD over your analog video feed, and has a switchable 10 V rail so you can power your VTX from it.

The firmware this board runs on
Betaflight is community firmware we didn't write, and it is what makes this board fly.

- Not a toy. Not for persons under 14; minors only under adult supervision.
- Component for self-built unmanned aircraft: the builder is responsible for the assembled aircraft and its lawful operation.
- LiPo batteries can ignite when damaged, shorted or overcharged; never charge unattended.
- Remove propellers before bench testing, configuration or firmware updates.
- Observe the voltage and current limits in the specifications; reverse polarity destroys the board.
- Geen speelgoed. Niet voor personen onder 14 jaar; minderjarigen alleen onder toezicht van een volwassene.
- Component voor zelfgebouwde onbemande luchtvaartuigen: de bouwer is verantwoordelijk voor het samengestelde toestel en het wettige gebruik ervan.
- LiPo-batterijen kunnen ontbranden bij beschadiging, kortsluiting of overladen; laad nooit zonder toezicht.
- Verwijder propellers vóór benchtests, configuratie of firmware-updates.
- Respecteer de spannings- en stroomlimieten in de specificaties; omgekeerde polariteit vernietigt het board.
- Ceci n'est pas un jouet. Interdit aux moins de 14 ans ; mineurs uniquement sous surveillance d'un adulte.
- Composant pour aéronefs sans équipage auto-construits : le constructeur est responsable de l'appareil assemblé et de son utilisation licite.
- Les batteries LiPo peuvent s’enflammer en cas de dommage, de court-circuit ou de surcharge ; ne chargez jamais sans surveillance.
- Retirez les hélices avant les essais au banc, la configuration ou les mises à jour du firmware.
- Respectez les limites de tension et de courant des spécifications ; une inversion de polarité détruit la carte.
