Esi project: common questions

What microcontroller does the Esi project use?

The Esi project is built around the C701344, from the ESP32 family.

How big is the Esi project PCB?

The Esi project measures 130 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esi project?

54 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 Esi project design files?

From the alcaaron/esi_project 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 Esi project design in my own project?

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

Can I test firmware for the Esi project 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.
