Flysys test: common questions

What microcontroller does the Flysys test use?

The Flysys test is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the Flysys test PCB?

The Flysys test measures 90 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Flysys test?

64 components, from 31 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 Flysys test design files?

From the nejcokorn/flysys_test repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Flysys test design in my own project?

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

Can I test firmware for the Flysys test 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.
