Background

Syrostan project aims to test the quality and find out potential problems of the sinara project hardwares 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.


Basic information

Documents needed

  1. Altium Designer PCB project file (available on https://github.com/sinara-hw)

  2. Photos of the actual card with marks to specify where the test points are.

  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

Ordering steps

  1. Contact their customer service directly, providing them with the following:

  2. Pogo pins will occupy 15MM of inner space of the base box. A total height of 100MM should be enough to place the Syrostan board.

  3. Can ask them to add necessary buttons on the panel, especially one for detecting the pressing.

  4. Can ask for a dxf file of the holes on the acrylic they manufactured to import to KiCad for the extension PCB board.

  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

  7. The pogo pins are standard 2.54mm dupont pins. Connect the pogo pins and extension board with general female dupont connectors.
