Hi, I built a "normal" version, and soon I'll build a SMD version (both work similar)
Here is a Quick Start Manual: Link
Here a normal version assemble tutorial: Link
Here a SMD version assemble: Link
If you try pcbway see this: Link
If you prefer JLCPB you must buy and weld: 200R SMD resistor, 5V regulator and 10V 1000UF electrolytic capacitor.
