ESPLionV1: common questions

What microcontroller does the ESPLionV1 use?

The ESPLionV1 is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the ESPLionV1 PCB?

The ESPLionV1 measures 45 × 35 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESPLionV1?

114 components, from 37 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 ESPLionV1 design files?

From the Angus-McIntyre/ESPLionV1 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 ESPLionV1 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which Angus-McIntyre chose for the repository.

Can I test firmware for the ESPLionV1 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.
