Esp: common questions

What microcontroller does the Esp use?

The Esp is built around the 2x DF40C-100DS-0.4V, from the Raspberry Pi family.

How big is the Esp PCB?

The Esp measures 86.5 × 64.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp?

91 components, from 55 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 Esp design files?

From the jayadeep14/esp 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 Esp design in my own project?

The repository has no license, so all rights stay with jayadeep14. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
