[[Exidiophone]]をもっと小さくするUSB充電バッテリー化
(V4,5は失敗作として世に出ぬまま放り出されました)
バッテリーモジュール
[[TP4056]]系を使うと良さそう。
[GitHub - alltheworld/tp4056: TP4056 charger kicad schematics](https://github.com/alltheworld/tp4056)
5V昇圧モジュールも組み合わせたい
[LTC3426 Datasheet and Product Info \| Analog Devices](https://www.analog.com/en/products/ltc3426.html)
これかな
2枚のモジュールでバッテリーを挟み込む形に、1枚は電源管理、もう1枚はオーディオ
表面実装片面だけで済むようにすればDIYもしやすい裏面をGNDベタにすればシールドも十分そう
