WiFi KeyMouse: common questions

What microcontroller does the WiFi KeyMouse use?

The WiFi KeyMouse is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the WiFi KeyMouse PCB?

The WiFi KeyMouse measures 20 × 42.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WiFi KeyMouse?

26 components, from 19 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 WiFi KeyMouse design files?

From the 74th/74th-oshw-projects 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 WiFi KeyMouse design in my own project?

Yes, under the terms of its MIT license, which 74th chose for the repository.

Can I test firmware for the WiFi KeyMouse 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.
