The STM32 is 5V-tolerant, so probably nothing to worry about on that end. Maybe more of a question if the Shield gets the voltage it needs. It probably will, because the arduino headers have a pin reserved for 5V. It's just one of those things worth double checking, though, before you start banging your head against the wall....<br></font></div><div class="gmail_default"><font size="2">Maybe more worth noting is the fact that the shield uses the L293 motor driver (not the 298). The L293 is not exactly very powerful. 1.2A max.<br></font></div><div class="gmail_default"><font size="2"><br></font></div><div class="gmail_default"><font size="2">P.S.: what happened to your plans with Pi + Ubuntu + ROS ? Is the STM32 an addition to that setup, or instead of that Pi-based setup?</font></div><div class="gmail_default"><font size="2"><br></font></div><div class="gmail_default"><font size="2">Chris.<br></font></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Oct 21, 2021 at 3:19 PM Thalanayar Muthukumar <<a href="mailto:tnkumar@gmail.com">tnkumar@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Thanks Chris. <br>I have this Arduino shield (<a href="https://www.amazon.com/gp/product/B01LX9TLP5/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1" target="_blank">https://www.amazon.com/gp/product/B01LX9TLP5/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1</a>) which can possibly be used with the NUCLEO - I may need to confirm that the voltage levels match.
