     24<p>
     25The <b style="color:#000;background:#ffff66">Ventana</b> has a very robust <b style="color:#000;background:#66ffff">power</b> supply for Wireless Radios in the Mini-PCIe slot.
     26</p>
     27<p>
     28The 3.3V can be accessed in a few other places:
     29</p>
     30<ul><li>JTAG Header - 1A maximum per pin (see user manual)
     31</li><li>DIO Connector (see below)
     32</li></ul><h2 id="a5VSupply">5V Supply</h2>
     33<p>
     34The <b style="color:#000;background:#ffff66">Ventana</b> has a smaller 5V supply typically for USB.
     35</p>
     36<p>
     37The typical 5V supply is only 1.5A.
     38</p>
     39<h2 id="DIOConnectorforPower">DIO Connector for <b style="color:#000;background:#66ffff">Power</b></h2>
     40<p>
     41The JST DIO connector on the <b style="color:#000;background:#ffff66">Ventana</b> boards has pins rated for 3A maximum. Supplies source may vary.
