The original idea of this project is to use the unused 18650 batteries at the lowest cost so that they can continue to shine and heat (not literally), so the initial priority adaptation solutions are relatively cheap 5V2A solutions, 18W and PD are also included. Adaptation is in progress, and is expected to be released in the long future (gugugu)
Position-related: The kit was purchased from a certain tb store, which has no interest in me, and I don’t know the
current price of purchasing the shell alone. It’s 8 per piece with free shipping. I think it’s relatively cost-effective and acceptable, so I plan to adapt this shell
to the drawing board to make the finished product. When placing an order to buy the shell, be sure to ask the boss to check the light guide sheet, buttons, and screws to ensure that they are not missed. , when I bought it, the seller failed to provide me with these materials several times.
Currently, I have made many board tests and tried my best to make the part of the PCB corresponding to the shell opening as accurate as possible. Many of them were measured manually, so there must be some. Error, I hope you can understand.
It would be better if you can help feedback some questions. Thank you very much!
This account is specially used for open source projects, and the response is relatively slow. You can also contact @奕有有什么 to provide feedback.

USB wireless network card-RTL8188 module adapter board (adapted to U disk shell) New
----------Introduction----------
As the name suggests, this project is an adapter board that recycles idle RTL8188 modules. Although it is not fast, it is enough for emergency or non-pursuit purposes. Speed of device usage.
Win10 driver-free plug and play! ! Win7 needs drivers! ! Drivers are provided for MacOS but have not been tested! !
The real thing has been printed and verified, but I changed my phone too frequently and couldn't find the picture. I will wait for a while and re-print the purple board to make up for it.
This project is a reset and updated version of the RTL8188 USB network card universal U disk board project, with minor modifications and two different versions of the U disk universal version shell and G2 shell.
Only one version of the antenna is retained. If you need an external or onboard antenna, you can modify it yourself.
If you have any questions, you can report them in the comments, although I may not necessarily correct them* or directly contact @啕有有什么 to give feedback.
----------I don't have this module, but I want to do this little thing. How do I get it? ----------
The wild RTL8188 wireless module can generally be found in TV set-top boxes, some cottage boards, copycat netbooks, surveillance cameras, low-end drones (toy-grade ones), and other equipment.
I personally don’t think it’s very cost-effective to buy a new tb to do this, but even if you buy a new one, the cost is still only more than ten yuan.
----------Other notes and Q&A----------
1. Regarding the issue of whether MacOS can be used, after checking some sellers who sell modules and black Apple forums, I got most of them. The results all indicate that it can be used under MacOS, but unfortunately I don’t have a Mac at the moment so I can’t test it. If it works after testing, I hope you can give me your feedback in the comments. Thank you very much. (MacOS driver is included in the attachment).
2. Regarding the problem of feedback heating in the old project, after 5 minutes of inquiry, another merchant said that 1117 cannot be used for this module and can only use DCDC. The specific reason is not clear at the moment. I hope you can answer it.
3. I have no knowledge or experience in antenna design, and the antenna on the PCB is based on the on-board Wifi antenna. There will definitely be some unreasonable things. I hope someone can correct it.
4. Some of the information and some drivers I found have been shared in the attachment. If you need it, you can download it according to your own needs. The network card is driver-free under Win10, but Win7 requires a driver.

DCDC boost module-B628 or SX1308
Introduction: DCDC power module, boost, using B628 (SX1308) chip solution
DCDC power module, boost, uses B628 (SX1308) chip solution. All the materials are needed to make a module. It only costs a few yuan per module, which is not expensive.
The input voltage range of the B628 chip is 2V-24V, and the output voltage can be adjusted to 28V. I have this one. It seems that the maximum is more than 20. If you need other voltages, you can change the feedback resistor and circuit according to the specifications.
Many of the boost modules of Aubao have the same chip solution. Don't believe the so-called output of 2A. It is not that fierce.
The same circuit has been sampled and tested. This The board is just redrawn to a size of 3x3cm, which is fine in theory. The actual picture will be supplemented with
low power in the future, which is suitable for boosting power supply for small things such as router optical modems. Generally, 0.0 A for routers or optical modems is enough. . 5V input and 12V output will be warm at about 1A. If it is higher, it is recommended to stick a heat sink on the back.
This thing is not technical. It is just buying too many chips and making a board to make a module. The input interface can be ph2.0, micro or typec
