STM32 lower power consumption

2022-05-23
Hi everyone, I need the lowest possible current consumption for my project. I need to power my MCU with external supply. Currently I have a Nucleo F401RE, which is not so good for low power applications it seems. It's connected to a X-NUCLEO-NFC04A1 ...

3.3V external power supply

2022-04-06
Hi everyone, I need to power my F401RE with a 3.3V external power source. I read in the datasheet I need to connect the power source to the CN7 pin 12 or CN7 pin 16. Where do I connect GND signal apart from 3.3V signal?Also, from what I understood, I...

Nucleo F401RE Sleep Mode and X-NUCLEO-NFC04A1 tag

2022-03-17
Hi everyone,I'm trying to understand if it's possible to use the sleep mode of the F401RE and then restore its state as soon as a NFC reader polls for the tag.From what I understood, the NFC04A1 tag has a built-in mechanism that triggers interrupts b...

Impedance matching circuitry on X-NUCLEO-NFC03A1

2022-03-04
Hi everyone,I'm facing some issues while trying to understand if (and eventually how) it's possible to use a different antenna using an X-NUCLEO-NFC03A1 evaluation board.I know I may just use the bare ST25R95 chip and then realize an impedance matchi...

How to use FTM to READ mailbox using a X-NUCLEO-NFC03A1 kit?

2022-02-23
Hello,I'm facing problems thinking about how to read RF data using my 03A1 reader using FTM.My main point is to see if I can decrease RF reading times of a message (8 bytes, so really short) using the ISO15693 standard.My first firmware uses 04A1 tag...
