<p>I would like to make a 24&nbsp;V (3D printer board and shield) setup, as opposed to the usual 12&nbsp;V, and to do so I had been considering using the Taurino Power board, or the clone Eruduino. However, I just found this board:</p>

<p><a href="https://i.stack.imgur.com/FoUYh.jpg" rel="nofollow noreferrer" title="Re-ARM microcontroller, with SD card slot"><img src="https://i.stack.imgur.com/FoUYh.jpg" alt="Re-ARM microcontroller, with SD card slot" title="Re-ARM microcontroller, with SD card slot"></a></p>

<p>The specifications state a DC input of up to 36&nbsp;V:</p>

<p>Does anyone know whether that <em>really</em> means it can handle 24&nbsp;V in the same manner as the Taurino/Eruduino? If so, then that looks like a double win: not only 24&nbsp;V support, but also a faster processor. Anyone have experience with this board?</p>

<p>I was thinking of using with a RAMPS1.6 Plus (maybe), or just a regular RAMPS 1.4 (<a href="https://reprap.org/wiki/RAMPS_24v" rel="nofollow noreferrer">hacked to support 24&nbsp;V</a>). I'm just shopping about, and I thought that if I was going to spend £14 on an Eruduino, then I just as well spend that money on something better.</p>

<p>It does work with Marlin apparently, as some of the customer reviews would suggest, but none of the reviews that I could find referred to a 24&nbsp;V setup (heated bed etc.), hence my question.</p>
