I bought a book a while ago and got a small Arduino board as a gift. I took it back and took a look! Go ahead, such an old-fashioned power input port~
I can't even find a charger with a round mouth. This board can only be used to eat dust! ~
I've thought about this again in the past two days, so I might as well draw a transfer board!
Now you can directly convert the round DC port into a TypeC port or MicroUSB port
Note that it does not have data transmission function. There is no data cable for the DC port either!
When making the board, you only need to drill 1.0mm, and it will break as soon as you snap it in the middle, which is very convenient!
Please refer to pictures for the effect:)
