Hi,
I'm trying to connect a X-NUCLEO-LPM01A (https://www.st.com/en/evaluation-tools/x-nucleo-lpm01a.html) to a B-L475E-IOT01A (https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-discovery-kits/b-l475e-iot01a.html)
My B-L475E-IOT01A card does not seem to start (I'm writing a bit of code to verify this).
When looking at the schematics, the card need a 5V input but all the components I use are connected to the 3.3V input and should be able to run without all the card running.
Is there a way to make this work with a 3.3V input or to plug a 5V input on the card and still monitor the consumption (using another card maybe) ?
EDIT : I also posted this question on the ARM MBED Forum (https://forums.mbed.com/t/monitoring-energy-consumption-on-a-b-l475e-iot01a/12242)
