ldcyes/OpenDuck
已完成可编辑原理图、真实四层 PCB 和本地库。阶梯板面积 4510 mm²,比原 65×60 + 32×30 mm 两板总面积 4860 mm² 少 350 mm²(7.20%)。原 TDK 模块本体、四个安装孔和原 TDK 器件位置保留,回生电容采用原料号卧装,J1 因实际拔插通道冲突改为同系列 BM08 顶插。当前为工程候选,未制造,未完成热、回生瞬态、低电量或行走验收。


Majorwhiskey/gps-lora
Theoros is a USB-C GPS logger and LoRa tracker built on the ESP32-S3. It logs 1 Hz u-blox M10 fixes to microSD, shows status on an OLED and sends AES-128-CCM encrypted position over 868 MHz LoRa.

It measures 72 × 52 mm and has 2 copper layers, 1.6 mm thick.
78 parts, built around the MDBT42Q-512KV2, LIS3DH, RFM95W-868S2 and SM351LT. 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.
From the zbockaj/GarageNotifier-PCB repository on GitHub, at the commit this page was made from: the board is GarageNotifier.kicad_pcb and its schematic GarageNotifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask zbockaj before reusing the design.
