You can reset the board with a short click and enter the bootloader with a long (&gt;500ms) click of the button. This backwards compatiblility also enables you to use reset buttons on existing keyboards for both functions. <a href="/instructions/0xcb-helios/guide/reset_hu_7f27a6651db89c11.webp" class="glightbox"><span class="blur-up-wrap"><img class="blur-up-lqip" src="data:image/webp;base64,UklGRmwAAABXRUJQVlA4IGAAAADQAwCdASoUAAsAP1mKtkspJKKYBACTFYTzgGFAD1q3O2grGiiRaoAA4iuMxB1yWbmNh/oiIkpyUBkIGOwbX/aOqjZ8&#43;rlQ/Ao750XDgYiE&#43;UVG2cb&#43;F1LvfuMebSZAAAA=" aria-hidden="true" alt="" ><img src="/instructions/0xcb-helios/guide/reset_hu_7f27a6651db89c11.webp" width="1812" height="1020" decoding="async" loading="lazy" fetchpriority="auto" alt="reset" id="h-rh-i-0" class="blur-up" ></span></a> </p>/instructions/0xcb-helios/infos/Tue, 06 Oct 2020 08:48:45 +0000/instructions/0xcb-helios/infos/<h2 id="vendors">Vendors</h2> <p>Here are the Vendors, where you can get Helios.</p> <p>EU:</p> <ul> <li> <a class="link link--text" href="https://keeb.supply/products/0xcb-helios" rel="external">KeebSupply</a></li> <li> <a class="link link--text" href="https://keycapsss.com/keyboard-parts/mcu-controller/257/0xcb-helios-pro-micro/elite-c-compatible-microcontroller-with-rp2040" rel="external">Keycapsss</a></li> </ul> <p>Worldwide:</p> <ul> <li>US: <a class="link link--text" href="https://ringerkeys.com/products/0xcb-helios" rel="external">RingerKeys</a></li> <li>Canada: <a class="link link--text" href="https://rndkbd.com/products/0xcb-helios-microcontroller" rel="external">RNDKBD</a></li> </ul> <h2 id="changelog">Changelog</h2> <pre class="mermaid"> gantt title Helios Roadmap todayMarker off dateFormat YYYY-MM-DD axisFormat %d.%m.%Y section v1.0 dev :2022-07-28, 22w R1 :2022-12-28, 2023-02-26 R2 :2023-02-26, 2023-07-02 section v1.0 (CST) dev :2023-04-28, 2023-09-09 R3 A stock :2023-09-09, 2023-11-10 R3 B stock :2023-09-09, 2023-11-25 hotfix :2023-07-10, 60d R4 :2023-11-06, 2024-08-25 R5 :2024-08-25, 2024-12-30 R6 :2024-12-30, 2025-07-09 R7 :2025-07-09, 2026-01-24 R8 :2026-01-24, 30d </pre> <hr> <ul> <li>v1.0 [First version of Helios] <ul> <li>Round 1 <ul> <li>Supplied A stock to KeebSupply</li> </ul> </li> <li>Round 2 <ul> <li>Supplied A stock to KeebSupply</li> <li>Supplied A stock to RingerKeys</li> <li>Supplied A stock to Keycapsss</li> </ul> </li> </ul> </li> </ul> <hr> <ul> <li>v1.0 (CST) [Added castellated pads] <ul> <li>Round 3 <ul> <li>Supplied A stock to KeebSupply</li> <li>Supplied B stock to KeebSupply due to manufacturing issues</li> <li>Supplied A stock to RingerKeys</li> <li>Supplied A stock to Keycapsss</li> </ul> </li> <li>Round 4 [improved manufacturability of the castellated pads] <ul> <li>Supplied A stock to KeebSupply</li> <li>Supplied A stock to Keycapsss</li> <li>Supplied A stock to RNDKBD</li> </ul> </li> <li>Round 5 [Added purple and white Helios options] <ul> <li>Supplied A stock to KeebSupply</li> <li>Supplied A stock to Keycapsss</li> <li>Supplied A stock to RingerKeys</li> </ul> </li> <li>Round 6 [More black units] <ul> <li>Supplied A stock to KeebSupply</li> <li>Supplied A stock to Keycapsss</li> <li>Supplied A stock to RingerKeys</li> <li>Supplied A stock to RNDKBD</li> </ul> </li> <li>Round 7 [Way more black units] <ul> <li>Supplied A stock to KeebSupply</li> <li>Supplied A stock to Keycapsss</li> </ul> </li> <li>Round 8 [More purple and white units] <ul> <li>Supplied A stock to KeebSupply</li> </ul> </li> </ul> </li> </ul> <hr>
