First try for a novice, size: 3.8*3.6
If the cost is well controlled, it only costs less than five yuan.
There were two double-layer ports left before, so I just made use of them. In view of the battery problems of mobile devices (mobile phones and tablets), a type-c separate power supply was added (can be switched by a switch)
If you don’t need a separate power supply, you don’t need to solder the type-c 6p and switch (just use a piece of tin to connect them directly)
With the addition of an indicator light, you can choose other resistance values to obtain appropriate brightness (no welding required)
