Hpi baja: common questions

What microcontroller does the Hpi baja use?

The Hpi baja is built around the ESP32-S3-WROOM-2, from the ESP32 family.

How big is the Hpi baja PCB?

The Hpi baja measures 90.2 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hpi baja?

15 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hpi baja design files?

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

Can I use the Hpi baja design in my own project?

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

Can I test firmware for the Hpi baja 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.
