MAZEBLAZE-V3: common questions

What microcontroller does the MAZEBLAZE-V3 use?

The MAZEBLAZE-V3 is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the MAZEBLAZE-V3 PCB?

The MAZEBLAZE-V3 measures 111.4 × 88.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MAZEBLAZE-V3?

22 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the MAZEBLAZE-V3 design files?

From the SurajSonawane2415/MazeBlaze repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MAZEBLAZE-V3 design in my own project?

The repository has no license, so all rights stay with SurajSonawane2415. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MAZEBLAZE-V3 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.
