<ul>
<li><a href="https://shop.m5stack.com/products/atomic-h-bridge-driver-base-drv8876" target="_blank" rel="noopener noreferrer nofollow ugc">H-Driver</a></li>
<li><a href="https://shop.m5stack.com/products/atom-socket-kit-hlw8023-jp-us?variant=39295191744684" target="_blank" rel="noopener noreferrer nofollow ugc">Atom Socket</a></li>
</ul>
<p dir="auto">They both run nicely being controlled over MQTT or BLE.</p>
<p dir="auto">But any devices connected that need power are receiving a quick amount<br />
of power when the <code>M5Atom</code> is turned on. This occurs before my software runs - so before I can decide whether the power should be on or off.</p>
<p dir="auto">So for the <code>H-Driver</code>, the connected small motor gets a quick jolt of power before my software runs. For the <code>Atom Socket</code>, the same quick power on occurs (turning on the connected device) before my software can determine the correct on/off mode.</p>
<p dir="auto">Is there any way to stop this? It's not good (actually it's rather bad).</p>
<p dir="auto">Thanks,</p>
