Autonomous Drift Cart: common questions

What microcontroller does the Autonomous Drift Cart use?

The Autonomous Drift Cart is built around the RC Pico, from the RP2040/RP2350 family.

How big is the Autonomous Drift Cart PCB?

The Autonomous Drift Cart measures 185.2 × 141.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Autonomous Drift Cart?

116 components, from 29 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 Autonomous Drift Cart design files?

From the danielwilczak101/EasyDrift 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 Autonomous Drift Cart design in my own project?

The repository has no license, so all rights stay with danielwilczak101. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Autonomous Drift Cart 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.
