According to an UP owner at station B ( [[self-made] young man's first FOC driver] ) , most of the components are 0805, which are available in the laboratory and are easy to solder by yourself.
The crystal oscillator uses a passive crystal oscillator, which is large in size, and can be modified by yourself to an active crystal oscillator of 4-16M.
