A personal carry device in the shape of a carrot, Carrie is an interpretation of the carrot pen used by Judy Hopps in Zootopia. It's built with a microphone and a camera, integrated into the tiny form factor of a pen, and powered by an embedded Linux microcontroller (Luckfox Pico Mini B) on a custom PCB. With the click of a button, Carrie records 1080p footage at 30 FPS with audio, making sure you never forget to…

Dirt: common questions

What microcontroller does the Dirt use?

The Dirt is built around the SEEED_113990105, from the ESP8266 family.

How big is the Dirt PCB?

The Dirt measures 60.7 × 53.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dirt?

19 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Dirt design files?

From the Fangoboyo/carrie-shenzhen repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Dirt design in my own project?

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

Can I test firmware for the Dirt without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
