Hello everyone,
I'm starting an IoT project. It's a device that will measure some variables and send them over WiFi to a server. The device will have a small 2.4" TFT screen with an SPI interface, as it has an internal ST7735, and it will be powered by a 3.7V battery. I've been searching for the best NXP MCU option for many days, but there are so many good MCUs and too much information that I'm afraid I might make a wrong choice. What MCU would you recommend for my application?
It's not necessary for the MCU to have integrated WiFi modules; I just need it to have very low power consumption in run mode and a USB device interface.
Regards.
Solved! Go to Solution.

Hi @MartinEnG ,
Thank you for your interest in the NXP product, I would like to provide service for you.
From your description, in fact, you are very care about the low power.
You mainly need the MCU which can support:
low power
SPI interface
WIFI interface, maybe you can use the UART, SDHC method interface
3.3V power
USB
To these requirement, I think so many MCU chips in the NXP can meet your requirement, you don't need to use the I.MX processor, that is very higher level to you.
You can consider： kinetis L series, LPC series, I.MX RT101x series.
Wish it helps you!
If you still have questions about it, please kindly let me know.
Best Regards,
Kerry

Hi @kerryzhou ,
Every chip is very good, and due to the cost, I think I will use the K32L2B31VFM0A, but I have a couple more questions. Are there any tools similar to Qt Designer for designing GUIs for the chip I mentioned? And, what is the MCU's lifespan?"

Hi @MartinEnG ,
NXP have Gui Guider:
https://www.nxp.com/design/software/development-software/gui-guider:GUI-GUIDER
But, it still didn't support K32L2B31VFM0A.
Maybe, you can consider the 3rd part Segger emwin:

Wish it helps you!
Best Regards,
Kerry
