Hey, wait a minute - there are much cheaper USB power meters on the market! What makes yours so special? Well, it's actually accurate.
You see - most USB power meters have measurement errors of 5% or more - and they often only display 3 significant digits. This is of course fine for just checking roughly how much power something is drawing, but for accurate energy measurements (e.g. debugging mobile apps, seeing how much power they draw over a longer period of time) you have to use tools that have well-defined accuracy specifications. This is your tool.
Even if you don't necessarily want to measure USB devices, you can use it for anything else, as long as the voltage stays between 4.1 and 20V. I have a useful little adapter board to tie this product to a removable terminal block.
If you want to use this product as a nice development board for the ATSAMD09D14A (with a snazzy OLED and some decent analog frontend circuitry), you can additionally buy the SWD to ribbon converter ($5 add-on) so you can use your Segger J-Link or other SWD debugger to program and debug the microcontroller on this board. Binaries of the default firmware are available.
This is a USB type-A modification of my USB type-C power meter.
