<p>as expected, we have trouble! it draws like 1.5 watts while the supply is sagging down to 3.6 V. those 1.5 watts are going somewhere, and it sure as heck isn't the STM32 or the ublox M8! time for some thermal imaging</p><p>the fusion is pretty bad at this distance, but it's probably this capacitor has broken down</p>
<p><span class="h-card" translate="no"><a href="https://masto.fuzzy.systems/@ChlorideCull" class="u-url mention">@<span>ChlorideCull</span></a></span> excellent question! how do i check?</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> I am very much looking forward to your analysis. 😀 Though I'd also have been very interested in workarounds of the protection mechanisms.</p>
<p>ok, now i just need to power it</p><p>conveniently, there is silk that explains how to do that</p><p>it uses an LDO, so i don't think i actually need +24V, probably anything above 5V will work. i'll hook it up to a current limited supply first</p>
