超能花钱鸭 Fanduck · Microduck 已复刻成功

基于官方项目完成复刻：本项目基于 Pollen Robotics 官方公开的 Microduck 代码 与 模型资料 制作。感谢官方团队的分享！

官方项目 · 官方官网 · 我们的官网

我们的 Microduck 已经复刻成功！ 从零件采购、3D 打印到装配与调试，我们完成了从 0 到 1 的实机复刻，下面的照片和视频就是这只鸭子的实拍。

Fanduck 是对 Pollen Robotics Microduck 的非官方个人研究复刻。这里分享本次复刻所用的制作资料：物料清单、打印文件、板件资料、制作工具，以及查看鸭子 3D 姿态的镜像工作台。资料与项目官网同步存放，方便大家参考和交流。

Questions

How big is the Dchub 4port strip v1 1 PCB?

It measures 43 × 13 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Dchub 4port strip v1 1 use?

6 parts, built around the B3B-EH-A(LF)(SN), EEU-FR1C471B and KF301-5.0-2P. 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 Dchub 4port strip v1 1 KiCad files?

From the 7757/fanduck repository on GitHub, at the commit this page was made from: the board is hardware/dchub-v1.1/source/dchub_4port_strip_v1_1.kicad_pcb and its schematic hardware/dchub-v1.1/source/dchub_4port_strip_v1_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Dchub 4port strip v1 1 design in my own project?

Its repository states no licence, so its author keeps all rights: ask 7757 before reusing the design.
