STM32F746G-DISCO Power Measurement

Hello,

I am interested in doing some power measurements on the STM32F746G-DISCO board. The most straightforward way to do this seems to be to measure the current powering the entire board. However, this does not seem very accurate, especially since I'm mainly interested in only the STM32F7 SoC itself (rather than the many other components on the board such as the Ethernet block, the external flash memory, etc).

Are there any test points on the board for performing more fine-grained power measurements? Does anyone else have any experience in performing power measurements on this board?

Thanks,

Harry Wagstaff

Hi Harry Wagstaff,

I recommend you to have a look to the PWR Current Consumption example under the STM32F7 cube firmware package:

STM32Cube_FW_F7_V1.4.0\Projects\STM32746G-Discovery\Examples\PWR\PWR_CurrentConsumption

In the readme file associated to the example, you find the board Set-up to measure the IDD current.
