BLE Voice<p>PSA for hardware tinkerers: JL (Jieli) chips use opaque silk-screen markings, but there’s a pattern! </p><p>🔹Serial (e.g., "AB18A"): Production date/batch—usually irrelevant. <br>🔹Part after "-" (e.g., "25B4"): The golden ticket! Search "25B" in Jieli’s catalog, then verify package type. </p><p>Most JL chips follow this, but some need factory help. Shared a full breakdown on my blog. </p><p><a href="https://mastodon.social/tags/JLchip" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>JLchip</span></a> <a href="https://mastodon.social/tags/Electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Electronics</span></a> <a href="https://mastodon.social/tags/EmbeddedDesign" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EmbeddedDesign</span></a> <a href="https://mastodon.social/tags/OpenHardware" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenHardware</span></a> <a href="https://mastodon.social/tags/PCB" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PCB</span></a> </p><p><a href="https://www.linkedin.com/pulse/interpretation-jl-jieli-chip-silk-printing-how-judge-junluan-tsui-tlzxc" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">linkedin.com/pulse/interpretat</span><span class="invisible">ion-jl-jieli-chip-silk-printing-how-judge-junluan-tsui-tlzxc</span></a></p>
