EnchantiS3: common questions
What microcontroller does the EnchantiS3 use?
The EnchantiS3 is built around the ESP32-S3-WROOM-2-N32R8V, from the ESP32 family.
How big is the EnchantiS3 PCB?
The EnchantiS3 measures 55.9 × 25.4 mm, has 4 copper layers and is 1.7124 mm thick.
How many components are on the EnchantiS3?
63 components, from 32 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 EnchantiS3 design files?
From the aburt2/EnchantiS3 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 EnchantiS3 design in my own project?
Yes, under the terms of its MIT license, which aburt2 chose for the repository.
Can I test firmware for the EnchantiS3 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.
