Syrostan project aims to test the quality and find out potential problems of the [sinara project hardwares](https://github.com/sinara-hw) manufactured by the factory. A lever is used to fix the cards and probe necessary test points through pogo pins. The document gives a guide on how to order these tailor-made levers for each card (taking DIO-SMA as an example) from Taobao.
