I saw that many friends found out that the third GND pin was not laid with copper correctly during the process of converting from AD to EDA, resulting in flying wires, so I open sourced the one I drew. It has been boarded and soldered, but it has not been tested online!
This version has been redrawn, adding screw fixing holes (m2), a spacing of 20mm (silk screen marking), and adding test points, so you can directly test flying leads without FPC.
