[[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。

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)
