 Gateworks builds very robust power supplies for its 3.3V rail. This rail is primarily used by the wireless radios on the Mini-PCI and Mini-PCIe slots.
 
-Most Ventana User Manuals indicate the wattage available to the Mini-PCIe sockets. 
+Most Ventana and Venice User Manuals indicate the wattage available to the Mini-PCIe sockets. 
+
 For example, under the standard features you will typically see:
  * 30W shared between all Mini-PCIe Sockets
  * 15W maximum per Mini-PCIe slot.
 
-On a Ventana series board with a 2x5 expansion connector, the pins are rated to 1 amp. Therefore, at 3.3V this would be 3.3W of support. Note that GPIO lines are limited in current, please consult the user manual.

-To find current ratings of the pins, consult the connectors datasheet.

+ * 3.3V supply supports up to 6A total for the entire board, shared across everything
+  * Pin 9 on J5 on the Venice GW7200 is connected straight to the 3.3V supply and thus can supply the pin and connector maximum. The JST B10B-PASK-1 LF SN is rated to 3A.
