版本与装配边界

KiCad 三个主文件与 2026-09-16 最终制板记录逐字节相同。本次整理未修改网络、铜线或器件位置,也没有生成新的投板修订。

实物屏幕接口 J2 曾旋转 180° 返修;这个改动尚未写回 KiCad,不能把当前生产图当作已修正的屏幕装配方向。FH12 立式插座要求排线金属接触面背向棕色锁扣;具体针序与原理图同时核对,不能只翻排线上电。下一次 PCB 修订需把实物接口修正纳入设计并重新审图。

V3-SLA 修复外壳 USB 左右镜像与 PCB 装入时的螺丝柱干涉,需要成套替换主壳、底盖和扬声器托架。CAD 检查已通过,树脂打印后的实际试装、线束弯折与螺纹强度仍待验证。先打印入口框和底盖,不将装配 STEP 当作单件打印模型。

lib/ 只保留当前主工程使用的三个项目封装及符号库;标准库和标准 3D 模型由 KiCad 10 提供。J2 等自定义器件未绑定完整厂家三维模型;结构校验使用 PCB 平面数据与保守高度包络,不等于完整厂家装配模型。

GitHub 保存展开文件,不同时保存 ZIP 副本。生产方需要 ZIP 时,仅压缩制造目录的生产文件;结构打印包可用 mechanical/V3-SLA/source/package.py --output <工程目录外的路径> 生成。

Questions

How big is the VoxConductor PCB?

It measures 52 × 50 mm and has 4 copper layers, 1.61 mm thick.

What parts does the VoxConductor use?

64 parts, built around the ESP32-S3-WROOM-1-N8, MAX98357AETE+T, TLV62569DBV and INMP441ACEZ-R7. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the VoxConductor KiCad files?

From the LighthouseXy/VoxConductor repository on GitHub, at the commit this page was made from: the board is hardware/VoxConductor.kicad_pcb and its schematic hardware/VoxConductor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the VoxConductor design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
