tools/ 为此次整改的重建和检查脚本;日常直接编辑 KiCad 工程。重建脚本会覆盖设计,不能在人工修改后直接重跑。Python 工具不引入继承类;需要 KiCad 10 的 pcbnew Python,以及 Python 3 的 sexpdata、numpy、scipy、shapely、pymupdf。

固件接口和采集协议保持 F302 版本兼容,编号 E7 不意味着更改串口协议。有效采集前等待模拟偏置稳定,首板按 first_board_tests.csv 验证。

量产前复核见 review/preproduction/report.md。工程根目录 BOM.csv 为逐位号明细,BOM_采购汇总.csv 为 39 种料号的中文采购汇总,均包含简要参数及立创商城编码;单板共 153 个装配器件。实时库存、贴片库可用性及实物验证待确认。

Questions

How big is the Ir glasses EVT E7 PCB?

It measures 152.3 × 72 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Ir glasses EVT E7 use?

171 parts, built around the STM32F302CCT6, TLC59283RGER, TLV9061IDBVR-MS and LSM6DS3TR-C. 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 Ir glasses EVT E7 KiCad files?

From the noahzhy/cc_glasses repository on GitHub, at the commit this page was made from: the board is hardware/ir_glasses/ir_glasses_EVT_E7/ir_glasses_EVT_E7.kicad_pcb and its schematic hardware/ir_glasses/ir_glasses_EVT_E7/ir_glasses_EVT_E7.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ir glasses EVT E7 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).
