NeerSync: common questions

What microcontroller does the NeerSync use?

The NeerSync is built around the ESP32-WROOM-32D, from the ESP32 family.

How many components are on the NeerSync?

12 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the NeerSync design files?

From the amannsaini0507-max/NeerSync repository on GitHub, which has a netlist; the links under Design files point to each one.

Can I use the NeerSync design in my own project?

Yes, under the terms of its MIT license, which amannsaini0507-max chose for the repository.

Can I test firmware for the NeerSync 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.
