+
+Need ~1 week for manufacturing
+
+Price mainly based on numbers of test points (need to confirm with the shop owner, for DIO case, they charged 400RMB for 60 test points)
+
+Ask them to ship to HK directly using SF-express (weight ~5kg, shipping fee 70~120HKD)
+
+**Documents needed:**
+
+
+
+1. Altium Designer PCB project file (available on [https://github.com/sinara-hw](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](https://git.m-labs.hk/sinara-hw/Syrostan-HW)

+
+**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](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.
