## thinking

So far, the chinese version pyboard 1.1 plus is the best. It has 60+ free pin for using, and it has built-in SD card loader. And when you connect your chip to computer, it will show you a storage where you can directly change the main.py in your flash storage or SD card storage to do the programming.
