Wireless Mouse PCB

A redesigned 4-layer PCB, laid out in KiCad to fit the OEM Logitech G Pro X Superlight shell, with contactless magnetic buttons and haptic feedback.

Tools: KiCad, stenciled solder paste, hotplate reflow

Overview

I redesigned the PCB shape and 4-layer layout in KiCad to fit the OEM Logitech G Pro X Superlight shell, adding contactless magnetic buttons and haptic feedback. I’m hand-assembling the board with stenciled solder paste and hotplate reflow of QFN and 0402 parts, and refined the design with professionals to resolve antenna, power, and clearance issues.
