From the project

Flight Controller for flying things based on RP2350A MCU

DragonFly Flight Controller is an open hardware, low-cost flight controller PCB and experimentation platform for UAV, drone, and embedded systems prototyping. This cost-optimised design uses a two-layer PCB, a budget-conscious bill of materials (BOM), and readily fabricated manufacturing files. Prototype boards were fabricated using the LionCircuits MII service.

Dragonfly v0-1 Ribs: common questions

What microcontroller does the Dragonfly v0-1 Ribs use?

The Dragonfly v0-1 Ribs is built around the RP2350_60QFN, from the RP2040/RP2350 family.

How big is the Dragonfly v0-1 Ribs PCB?

The Dragonfly v0-1 Ribs measures 52 × 71.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dragonfly v0-1 Ribs?

76 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dragonfly v0-1 Ribs design files?

From the aravindjayan/DragonFly_FC repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Dragonfly v0-1 Ribs design in my own project?
