And it&#39;s a Boosterpack (whatever that is)!</p><p>&nbsp;</p><p>I don&#39;t know what you intend for the tracking (please don&#39;t say it&#39;s going to be a job for an autorouter, entertaining though that might be), but wouldn&#39;t it work better if you rotated P3 (the output connector) by 180 degrees. It would then allow you to have the power ground (input gnd - GaN - output gnd) as copper on the top layer. Since all the power tracking could then be copper on the top, you might consider whether it would work well enough as a 2-layer board.</p><img src="https://community.element14.com/aggbug?PostID=1992&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/members-area/personalblogs/b/blog/posts/hercules-launchpad-and-gan-fets---part-2-make-a-boosterpackMon, 12 Sep 2016 18:31:37 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:ced00237-a7e2-4b2d-88f0-3e1124f93a11DAB1<p>Nice update.</p><p>&nbsp;</p><p>I like the idea of using a SBC to provide your PWM signals.</p><p>&nbsp;</p><p>That approach should give you solid control over the waveforms so that you can explore the reactions of the devices to various stimuli.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=1992&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">
