[STM32] The best RF Transceiver 433Mhz to use with STM32 boards - RF module

[Ayoub Cheggari]

Hi,

I wanna use an RF Transceiver 433khz with STM32 boards and I am looking for the best choices.

My requirements are very simple:

Frequecy supported 433Mhz

Multihoping strategy

SPI interface

I found the nRF905 but I am looking for a better solution.

Thanks,

Ayoub

You probably mean 433 MHz. Have a look at STM32WLxxx

Yes Right! I didn't notice! I'll check it. Thanks :)

hello @Ayoub Cheggari​  and welcome to st community .

I propose you to use one of those products :

• SPIRIT1 wish is  is a very low-power RF transceive.
• S2-LP wish is a high performance ultra-low power RF transceiver.

but the best solution is to use one of the products in the STM32WL Series wish are Long-range wireless STM32WL microcontrollers . more Precisely the stm32wl55jc2 is the best in your case .

Hope this is helpful .

Hi Issam,

Thanks for your reply!

I am really impressed by the WL series. I am an old user of STM32 but first time to hear about it.

I think these will do the job.

Thanks,

Hi Issam,

I actually rechecked the reference manual of the mcu and seems that the RF Tranceiver doesn't support the Multi-hopping strategy! Can you please confirm this?

I found a command for setting the frequency Set_RfFrequency() but I am not sure if it can do the job.

Thanks,
