Abstract
As for the raspberry PI 4B and 3B, besides the upgrade of processing performance, the interface has also changed a little. Let's have a look at it together. The charging power interface is changed from the original Micro USB of Raspberry PI 3B to the Type C interface of Raspberry PI 4B. The raspberry PI interface, the raspberry PI 3B interface is the standard HDMI interface, now the Raspberry PI 4B USES micro HDMI, I think it is to reduce the space volume.Another type of screen interface is the mini HDMI interface.Below presents the picture of 3 kinds of interface you can see.
