This article will introduce the difference between the S19 aluminum substrate and the PCB version from the following three aspects.
1. The control panel is different; the PCB version generally uses the 7007 control board, the aluminum substrate generally uses the A113D control board, the 7007 baffle is the card slot opening, and the A113D is the micro USB opening.
2. Hash boards are different, and the versions are distinguished based on this. For example, the PCB version is a common hash board, while the aluminum substrate version of the hash board is made of aluminum substrate.
