Picodrone: common questions

What microcontroller does the Picodrone use?

The Picodrone is built around the RPi Pico, from the RP2040/RP2350 family.

How big is the Picodrone PCB?

The Picodrone measures 35.6 × 71.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Picodrone?

32 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Picodrone design files?

From the bradley-ray/picodrone repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Picodrone design in my own project?

The repository has no license, so all rights stay with bradley-ray. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Picodrone without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
