The 3.3V can be accessed in a few other places:

  • JTAG Header - 1A maximum per pin (see user manual)
  • DIO Connector (see below)

5V Supply

The Ventana has a smaller 5V supply typically for USB.

The typical 5V supply is only 1.5A.

DIO Connector for Power

The JST DIO connector on the Ventana boards has pins rated for 3A maximum. Supplies source may vary.
