CarCANdy: common questions

What microcontroller does the CarCANdy use?

The CarCANdy is built around the ESP32-C3_SUPERMINI_TH, from the ESP32 family.

How big is the CarCANdy PCB?

The CarCANdy measures 110 × 68 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CarCANdy?

71 components, from 27 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 CarCANdy design files?

From the redt1de/CarCANdy 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 CarCANdy design in my own project?

The repository has no license, so all rights stay with redt1de. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CarCANdy 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.
