Ricardo-LightningMcQueen: common questions
What microcontroller does the Ricardo-LightningMcQueen use?
The Ricardo-LightningMcQueen is built around the ESP32-S3, from the ESP32 family.
How big is the Ricardo-LightningMcQueen PCB?
The Ricardo-LightningMcQueen measures 59 × 50 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Ricardo-LightningMcQueen?
135 components, from 83 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 Ricardo-LightningMcQueen design files?
From the icl-rocketry/Ricardo-LightningMcQueen 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 Ricardo-LightningMcQueen design in my own project?
The repository has no license, so all rights stay with icl-rocketry. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ricardo-LightningMcQueen without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
