[Upcycle It] Stay focused in the sky #2: Motor selection and power module/challenges-projects/design-challenges/upcycleit/b/blog/posts/upcycle-it-stay-focused-in-the-sky-2-motor-selection-and-power-moduleHi, I wanted since several days to write this post and show some of the interesting design choices taken in these days. First at all, initially I was having a choice to use a dc motor with encoder to control the movement of the telescope mount.&amp;...en-USTelligent Community 12RE: [Upcycle It] Stay focused in the sky #2: Motor selection and power modulehttps://community.element14.com/challenges-projects/design-challenges/upcycleit/b/blog/posts/upcycle-it-stay-focused-in-the-sky-2-motor-selection-and-power-moduleSat, 15 Apr 2017 03:37:01 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:43d75b81-2600-4ed5-9d09-ee27f0edb0acmcb11<p>There&#39;s another good reference here.</p><p><a class="jive-link-external-small" href="https://tronixlabs.com.au/news/tutorial-l298n-dual-motor-controller-module-2a-and-arduino/" rel="nofollow ugc noopener" target="_blank" title="https://tronixlabs.com.au/news/tutorial-l298n-dual-motor-controller-module-2a-and-arduino/">https://tronixlabs.com.au/news/tutorial-l298n-dual-motor-controller-module-2a-and-arduino/</a> </p><p>&nbsp;</p><p>ST have some good information, including using the L297 to drive the L298 and take away a lot of pain.</p><p><a class="jive-link-external-small" href="http://www.st.com/content/ccc/resource/technical/document/datasheet/f9/35/6e/3f/48/18/48/51/CD00000063.pdf/files/CD00000063.pdf/jcr:content/translations/en.CD00000063.pdf" rel="nofollow ugc noopener" target="_blank" title="http://www.st.com/content/ccc/resource/technical/document/datasheet/f9/35/6e/3f/48/18/48/51/CD00000063.pdf/files/CD00000063.pdf/jcr:content/translations/en.CD00000063.pdf">http://www.st.com/content/ccc/resource/technical/document/datasheet/f9/35/6e/3f/48/18/48/51/CD00000063.pdf/files/CD00000…</a> </p><p>&nbsp;</p><blockquote class="jive-quote"><p>actually there is a post that discourages to use the L298N driver with stepper motors</p></blockquote><p>Not sure where the idea that came from, but the L298 does require back EMF diodes, that are internal to some other versions.</p><p>&nbsp;</p><p>Mark</p><img src="https://community.element14.com/aggbug?PostID=2884&AppID=147&AppType=Weblog&ContentType=0" width="1" height="1">
