Single-chip wired keyboard to Bluetooth keyboard professional version

  This project converts a regular wired keyboard into a Bluetooth keyboard.
  Previous versions used the LCSC standard version; this version is the professional version
1.6 update (following the standard version update).
1. Uses the CH582F main controller. 
2. Optimized circuit structure with a more rigorous solution.
3. Replaced the battery charging chip, added a battery boost chip, and slightly optimized the TYPE and battery power switching circuit, remaining largely the same as before.
4. First time adding a casing; not yet fully designed
. 5. Now supports multimedia button uploads.

DRC (Ignore Antenna Section)
 
Version 1.7 Update:
1. Uses CH582F main controller
. 2. Corrects circuit bugs, fixes wired connection conflicting circuit logic, and fixes the issue of not being able to directly connect the keyboard via wire, etc.
3. Fixes program bugs and optimizes program structure
. 4. Regarding QMK firmware keyboard issues: Due to the high degree of customization of QMK, please ensure that your QMK keyboard's uploaded key value channel is endpoint one and the multimedia key channel is endpoint two; otherwise, unpredictable errors may occur.
5. Thanks to rc2064, yvling, etc. for their support and contributions to this project.
6. The module has been officially renamed HH90, and subsequent project releases will focus on software and schematics, no longer updating the PCB.
Manual Update:
1. Updated circuit and user manual version 1v2
   . Version 1v2 only updates the differences between the free and paid versions.
