DS lite Slot-2 蓝牙音频
Bluetooth Audio for Slot-2 on DS lite
Gbatemp 论坛用户正开发一款通过 Slot-2 为 DS lite 添加蓝牙音频的外部外设，项目目前仍在进行中。该外设采用 ESP32-PICO-D4 芯片，由 DS 的 Slot-2 3.3V 供电，需插入 Slot 2 与 3.5mm 耳机孔，可嵌入防尘盖。其缺点为游玩 GBA 游戏时无法使用蓝牙音频，且增加功耗可能缩短电池续航。
I'm working on an external peripheral that adds Bluetooth audio support to the DS lite powered by Slot-2.
The idea is a board that plugs into both the DS lite's Slot 2 and the regular 3.5mm headphone jack to transmit audio wirelessly.
Here's the mockup PCB I did in KiCad. It needs some refinements but it's made to fit in the DS-lite's included dust cover.
I'm using an ESP32-PICO-D4.
It would basically be one of these Bluetooth audio transmitters but powered by the DS' Slot-2 3.3V rail.
Pros:
- Sits flush with the DS lite
- Easy to install/use compared to internal mods
- Doesn't need external power.
Cons:
- Can't use bluetooth audio while playing GBA games.
- Increased power draw, potentially worse battery life.
Everything is still very much work in progress at the moment.
I prefer this over internal mods, but let me know what you guys think.

Like this? 
Yeah basically just like that ^^
Cool, can't wait for the video demo
Cool project!
How are you planning to init the bluetooth sync?
A button on the cartridge?
Awesome stuff, let me know if you need a shell designed for this

Do you know that Typing with Pokemon slot1 card has an internal bluetooth chip?
