Windows Hello face camera adapter board based on 0JCXG0

I saw this camera when I was browsing Taobao. The price is very cheap, only about 30 yuan, and it also supports Window Hello face recognition! This way, you no longer have to enter a password to open the computer, which is very convenient. And it still uses the USB protocol.

But I thought it was too ugly to fly the cable directly, so I decided to make an adapter board myself. When I searched for this connector... it was so expensive that it was enough to buy another camera, so I decided to fly the cable!

The overall peripheral circuit of the adapter board is very simple. It only needs to bring out VBUS USBD+ USBD- and GND. It also needs an LDO that converts the USB 5V power supply to 3.3V. Here I chose the popular AMS1117. Finally, I chose the extremely advanced Type-C interface and added a 5.1k pull-down resistor to the CC pin. In theory, it can be used by computers with Type-C (I am too poor to afford it)

It should be noted that the flying wires are located on several golden solder points above the connection base. The wire sequence is consistent with the wire sequence of the pads below. It is recommended to use enameled wire flying wires. The two subsequent pads are empty and do not need to be soldered.

Finally, just install the driver on the computer. See the attachment for the driver. When the following device appears in the device manager, it means success! Finally, we enable Windows Hello face recognition in the settings of win10 and enjoy the pleasure of face recognition.

(Don’t complain about the dark mosaic, but it’s really cool to have a classroom computer. Just turn it on and take a look.

Remark:

1. The pcb has been put into the popular layout. There is no problem in the actual test and can be prototyped. If it really can't pass, you can remove the base plate below. There is no via hole on the adapter board (so the flying lead pad can only be thrown underneath). The reason for cutting out the slots is that the bottom plate can be used as a baffle in extreme cases.
2. There are several GND pads on the board and the reason why the solder mask expansion is set to a negative number is to allow the board to lay copper, which can be ignored.
3. The copper pillars and screws can be M2.5 or M3. The height of the copper pillar can be 3mm. The actual measurement is just right.
4. There are several LED pads reserved on the control board. You can solder several bulingbuling LEDs according to your actual needs, and there are also corresponding patterns at the corresponding positions of the baffle (but try not to blackboard, as the light transmittance of the blackboard Not good, so I didn't weld).
5. Why are there two GNDs? Because the 5V and 3.3V power supplies on the board do not share the same ground... so you can only add one manually. Of course, if you find flying wires troublesome, you can also connect them together at the 0JCXG0 end.
6. I added a useless fuse... If you don't have it or don't want to solder it, you can use a piece of tin or delete it or short it with a 0 ohm resistor like I did.
7. It is recommended to use enameled wire for flying wire, which looks much better than ordinary wire.
8. Remember to turn on the driver! Otherwise, only an ordinary camera device will appear in the device manager, and the Windows Hello face function cannot be used.
