Models heart: common questions

What microcontroller does the Models heart use?

The Models heart is built around the C89297, from the ESP8266 family.

How big is the Models heart PCB?

The Models heart measures 29.9 × 32 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Models heart?

63 components, from 28 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 Models heart design files?

From the KushlaVR/models-heart repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Models heart design in my own project?

Yes, under the terms of its GPL-3.0 license, which KushlaVR chose for the repository.

Can I test firmware for the Models heart without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
