# WSMtool
A multitool adapter for the WonderSwan. Headphone, serial and link cable adapter in one.
## Idea
The idea for this multitool is to have a single adapter board which plugs into the EXT port of a WonderSwan and handle different tasks.
More specifically, this board can do the following:
* **Headphone adapter**: You can plug in regular headphones with a 3.5 mm connector and enjoy the enhanced 16b audio output.
* **Serial adapter**: Using the RP2040 Zero-based USB dongle board, you can use it as a PC serial adapter. You connect the WS adapter to the dongle via a male-to-male 3.5 mm cable (stereo cable) and connect the dongle via USB C to a computer. Useful for, e.g., WonderGate emulation, WonderWitch or ExtFriend.
* **Link cable**: Using the WSMtool link board, you can connect two WonderSwan and use a 3.5 mm audio cable (stereo) as a link cable.
## Usage
For regular headphone mode place the switch into a UP position.
For serial or link mode, place the switch into a DOWN position.
The RP2040 dongle works with [asie's ExtFriend](https://github.com/WonderfulToolchain/ws-extfriend).
It follows the same GPIO pinout, hence no changes in the code are required, it should work out of the box.
**ExtFriend Note**: The digital audio signals are not carried over to the dongle board.
This means the digital audio capture via ExtFriend is not possible.
**NOTE: NEVER connect two WonderSwan using two main boards or two link boards. Only connect two WonderSwan using one main board and one link board.**
**NOTE 2: Right now, the WSMtool is not compatible with my consolizer swancolorHD. DO NOT USE IT WITH swancolorHD!**
## Parts
The main and link board PCBs need to be ordered with 1.6 mm width to fit with the HDMI connector.

## Case
Right now, there are no cases for the WonderSwan adapters.
Though, there is a case for the dongle under the STL folder.
## Connector Sleeve
In order to make the connector better fitting, I designed a sleeve for the HDMI connector which "extends" it physically to a WonderSwan EXT connector. It's 3D printable, you can find the STL here in the repo.
## Disclaimer
**Use the files and/or schematics to build your own adapter board at your own risk**.
This adapter works fine for me, but it's a simple hobby project, so there is no liability for errors in the schematics and/or board files.
