Fluxguard: common questions

What microcontroller does the Fluxguard use?

The Fluxguard is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the Fluxguard PCB?

The Fluxguard measures 52 × 29 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Fluxguard?

34 components, from 16 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 Fluxguard design files?

From the lizuyi-6/fluxguard-pcb 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 Fluxguard design in my own project?

The repository has no license, so all rights stay with lizuyi-6. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Fluxguard 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.
