From the project
打开 q2-v2.kicadpro。这是 ESP32-S31NRV16 裸芯片版的独立工程，当前按用户要求改为 0402 阻容、电源分区铺铜并就近打过孔，信号待手动布线。不是可打板文件。原生产主板 hardware-q2` 的 PCB 保持原文件哈希。
打开 q2-v2.kicadpro。这是 ESP32-S31NRV16 裸芯片版的独立工程，当前按用户要求改为 0402 阻容、电源分区铺铜并就近打过孔，信号待手动布线。不是可打板文件。原生产主板 hardware-q2` 的 PCB 保持原文件哈希。
此前将 21 个电容、10 个电阻及 L105（实际为 0Ω 电阻）从英制 0201 改为 0402（公制 1005）；L101–L104 的射频/滤波电感不在阻容替换范围内。随后检查发现原嘉立创导入的 0402 与 KiCad 标准焊盘混用，现已统一全部 62 个电阻类封装（含 L105）及 72 个电容封装，原理图、符号库、PCB 和 3D 模型同步使用下面两套项目内标准封装。密集区已调整间距，接口和安装孔位置保持不变。
两者来自 KiCad 10 标准库，阻焊/锡膏使用标准继承设置。原有 0603/0805 电容和 1206 电流采样电阻保留原尺寸；过时的 134 个按位号命名的 0402 封装已移除，避免误用。0402-standardization.json 记录原始尺寸、统一后尺寸、位置及检查结果；运行 scripts/audit0402.py` 可核对所有实例的焊盘、阻焊/锡膏、模型及原理图关联。

Base: common questions
What microcontroller does the Base use?
The Base is built around the ESP32-S31NRV16, from the ESP32 family.
How big is the Base PCB?
The Base measures 46 × 76 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Base?
119 components, from 119 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 Base design files?
From the 0x616c6f6e/esp32s31-mp3 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Base design in my own project?
The repository has no license, so all rights stay with 0x616c6f6e. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Base 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.
