Corne Keyboard v4.1 fixes

Fixed a problem that made it unusable after miniaturization
- In v4.0.0, there was a problem that GND floated when the edge of the board was folded, making it unusable, but this problem has been fixed since v4.1.0.
Change of parts for TRRS connector
- The TRRS connector ( ST-0277D00-052-142 ) used in v4.0.0: has been discontinued and replaced by the PJ-399B-6A. As a result, from v4.1.0, TRS (3 poles) will be used for left-right communication. TRS (3 poles) is not supported in v4.0.0.

corne v4のTRRSコネクタの在庫が切れるかつ復活見込みが立たない状態になりましたが代替パーツを探して試作する段階まで来ました。安定供給が見込まれるパーツいくつか検討した結果TRSでHalf duplex通信になりますが何となりそうです。ついでにUSB_VBUS_PIN対応しました。 pic.twitter.com/OqCmSjz4jF

*If a board is manufactured using the V4.1.1 left-right intercommunication parts selected by default when ordering a board, it will not be compatible with a case created based on a V4.0.0 board. For products sold by Yousha-Kobo, the parts will be changed to compatible parts before being sold. Also, if you are designing a case, you may want to allow some margin for the TRS jack, as its position may be severe.

After all, the most significant modification is the ability to miniaturize.

Previously, there was a problem with the board not working when the edge of the board was folded, but now that this has been corrected, many people will be able to get their long-awaited mini conversion.

カットする部分のVCCを裏側に回して、表のベタGNDで中2段にGNDを回したのね(1枚目)

旧基板の白い範囲のGNDがmini化で浮いてたわけだ(2枚目)

旧基板もオレンジで示したところをバイパスすればminiで動きそうね(3枚目) pic.twitter.com/hxxy0cZwfO

In addition, the TRRS jacks used to connect the left and right sides are no longer in production, so they have been replaced with similar parts.

There are no changes to the case or board due to the connector change, only the firmware has been modified.

This also fixes the firmware.

The currently out-of-stock inventory of Yousha Kobo is also expected to be added as soon as it is ready.
