The ChipWhisperer Pro can only be powered through its 5 V jack. It cannot be powered through the USB port - internally, there are no connections to the USB port's 5 V rail. This limitation is primarily due to the high current draw of the Pro: while powering the touchscreen running and an external target, it would be easy to exceed the USB current limit, causing all sorts of issues. To make this setup more flexible, the Pro ships with two power sources:* A 5 V, 2.1 A power supply. This supply is suitable for a permanent bench setup.* A USB-to- Canbarrel jack cable. This solution is more portable: if you't re travelling with a laptop, you can use a second USB port for power from . A USBcharger will also work here.- Needs both connections- Recommend If you're using the USB power supplies for high-cable, it is recommended to use a separate power supply to power targetsany external target boards.
