LightWirelessMouse: common questions

What microcontroller does the LightWirelessMouse use?

The LightWirelessMouse is built around the ESP32-S3-WROOM-1U, from the ESP32 family.

How big is the LightWirelessMouse PCB?

The LightWirelessMouse measures 59.5 × 101 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LightWirelessMouse?

54 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the LightWirelessMouse design files?

From the davidjanoskyrepo/LightWirelessMouse repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LightWirelessMouse design in my own project?

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

Can I test firmware for the LightWirelessMouse 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.
