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.
3. Specify the shapes of the test points if necessary (especially for special shapes), such as holes, pads, holes with solder, pins of components, etc.
4. Specify which holes can be used to support the board (for DIO case, 4 screw holes are used)
5. The 3D cad file and photo of the Syronstan PCB (to show them the positions of screw holes)
Cad file could be exported from [https://git.m-labs.hk/sinara-hw/Syrostan-HW](https://git.m-labs.hk/sinara-hw/Syrostan-HW)
5. Ask them to take a video preview before shipping to us.
6. Extension board can refer to this example for DIO-SMA. [https://git.m-labs.hk/sinara-hw/Syrostan-Ext-DIO](https://git.m-labs.hk/sinara-hw/Syrostan-Ext-DIO)
7. The pogo pins are standard 2.54mm dupont pins. Connect the pogo pins and extension board with general female dupont connectors.
