i know most of the latest m.2 A+E key module is pcie x2 lane with USB are for lower power. I went to intel website for AC3168 as an example https://ark.intel.com/products/94854/Intel-Dual-Band-Wireless-AC-3168 Intel® Dual Band Wireless-AC 3168 Product Specifications but it doesn't show in specification how much power it uses during load, or average wattage.
I wish to know this as it is very important for me, please do not ask why, I just want to know for my own reasons which i do not wish to share.
these m.2 A+E key is 3.3v so w/e the current draw will be 3.3*mA.
