<h2 id="a3.3VSupply">3.3V Supply</h2>
<p>
The <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.
</p>
<p>
The 3.3V can be accessed in a few other places:
</p>
<ul><li>JTAG Header - 1A maximum per pin (see user manual)
</li><li>DIO Connector (see below)
</li></ul><h2 id="a5VSupply">5V Supply</h2>
<p>
The <b style="color:#000;background:#ffff66">Ventana</b> has a smaller 5V supply typically for USB.
</p>
<p>
The typical 5V supply is only 1.5A.
</p>
<h2 id="DIOConnectorforPower">DIO Connector for <b style="color:#000;background:#66ffff">Power</b></h2>
<p>
The JST DIO connector on the <b style="color:#000;background:#ffff66">Ventana</b> boards has pins rated for 3A maximum. Supplies source may vary.
