Neosword: common questions

What microcontroller does the Neosword use?

The Neosword is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Neosword PCB?

The Neosword measures 217.1 × 77.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Neosword?

70 components, from 35 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 Neosword design files?

From the wrickert/UntitledElectronics 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 Neosword design in my own project?

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

Can I test firmware for the Neosword 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.
