About the EnvOpenMouse PCB

EnvOpenMouse is an open source RP2040/RP2350 PCB design by Envious-Data, published on GitHub under the MIT license. It is a 2-layer board measuring 34 × 107.6 mm, with 64 components from 32 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the AP2112K-3.3, TLV70218DBVR and PMW3360DM-T2QU. By type, the board carries 20 capacitors, 16 connectors, 10 resistors, 9 switches, 4 ICs and 1 crystal.

From the project

An Open-source mouse for the UK market.

A lot of friends of mine would like something like a ploopyco mouse but there arent such options avaliable here in the UK and even then custom mouses as a whole is just not very popular.

This will be a open source mouse utilizting the PMW3360 and RP2040.

- Why the RP2040? Why not I say - Why PMW3360 - its easiest to get and is well known by the community meaning resources are avaliable.

EnvOpenMouse: common questions

What microcontroller does the EnvOpenMouse use?

The EnvOpenMouse is built around the RP2040, from the RP2040/RP2350 family.

How big is the EnvOpenMouse PCB?

The EnvOpenMouse measures 34 × 107.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EnvOpenMouse?

64 components, from 32 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 EnvOpenMouse design files?

From the Envious-Data/EnvOpenMouse 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 EnvOpenMouse design in my own project?

Yes, under the terms of its MIT license, which Envious-Data chose for the repository.

Can I test firmware for the EnvOpenMouse without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
