Donnay: USB 24-pin chart

<p>USB 24-pin chart</p>
<p><b>New page</b></p><div>== USB on the 24-Pin Flex Connector ==<br />
<br />
<br />
The 24-pin flex connector has USB port 1 on it. When you're looking at the verdex board as show below, pin one is on the left, and pin 24 is on the right.<br />
<br />
[[Image:Verdex-24-pin.jpg|thumb|24-pin flex connector orientation]]<br />
<br />
The connector is described [[Verdex_24pin_connector_chart|here]].<br />
The pinouts you need are:<br />
<br />
* V_BATT (pin 24) - USB power<br />
* USBH_N1 (pin 18) - USB D-<br />
* USBH_P1 (pin 17) - USB D+<br />
* GND (pin 8) - USB Ground<br />
<br />
In addition, you need to pull USBH_PWR1 (pin 20) up to 3.3 volts to enable the port. You need to provide a stable 3.3 volt supply, which is fairly simple to do by adding a small SOT23 package voltage regulator (like the LM3480), with the power input coming from V_BATT (pin 24) and the output going to USBH_PWR1 (pin 20).<br />
