About the Softswitcher module sw4
Softswitcher module sw4 is an open source RISC-V PCB design by oldsheeep3, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 40 × 100 mm, with 15 components from 9 distinct parts.
Its main chip is the CH32V003FXPX, from the RISC-V family. Other key parts include the XC6206P332MR-G. By type, the board carries 6 connectors, 4 switches, 3 capacitors and 2 ICs.
It belongs with the iot & wireless designs in this gallery.
From the project
HybridSwitcher — ハイブリッドIP映像スイッチャー（開発用リポジトリ）
既存機材（ATEM Mini）と自作ハードウェア（自作スイッチングモジュール群 + Pico 2W）、 ネットワーク技術（SRT / NDI / WebAPI）を融合した、次世代のハイブリッドIP映像スイッチャーシステム。
PC上に常駐する制御アプリを「脳」とし、複数プロトコル（UVC / NDI / SRT）の映像入力・PiP合成・ 仮想カメラ出力・タリー送出・外部機材（ATEM）の遠隔制御を一元化する。DIYでありながらプロ用 スイッチャーに匹敵する多人数オペレーション（メイン/サブ分業）と拡張性を目指す。
clone しただけの状態では、次の理由で初回ビルドが必ず落ちる。setup.sh がこれを一括で潰す。
未解決の問題が残ると終了コード 1 で終わるので、CI からそのまま呼べる（./setup.sh --ci）。

Softswitcher module sw4: common questions
What microcontroller does the Softswitcher module sw4 use?
The Softswitcher module sw4 is built around the CH32V003FXPX, from the RISC-V family.
How big is the Softswitcher module sw4?
The Softswitcher module sw4 measures 40 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Softswitcher module sw4?
15 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Softswitcher module sw4 design files?
From the oldsheeep3/TheHack repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Softswitcher module sw4 design in my own project?
Yes, under the terms of its GPL-2.0 license, which oldsheeep3 chose for the repository.
Can I test firmware for the Softswitcher module sw4 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
