Hello RIOT users,
Now I study how to use RIOT OS on the Nucleo-F446RE board.
Compiling sources, flashing elf file and inputting OS commands by pyterm is OK.
Next step is wireless communication between two boards. But Nucleo-F446RE board
does not equip RF.
Is it possible to connect RF board on the Nucleo-F446RE board ?.
If possible, which is the best sutable RF board for Nucleo-F446RE board ?.
Please inform me the RF board name, price and WEB-site to buy it.
I don't know about any shields specific to the Morpho connectors on the
Nucleo boards, but you can use any module with a supported radio chip
if you wire it up yourself with a bunch of jumper wires.
at86rf233 is a widely used and well supported chip,  has a cheap
module with it.
Another option is a mrf24j40 module. Those are a bit older but work
well too. You can get them on ebay or AliExpress.
Just note that the mrf24j40ma variant doesn't have a build-in amplifier
so the signal will not be as good as with mrf24j40md/e (the e variant
requires an external antenna though)
Hello Mr Valentin,
Thank you for useful information about RF module.
It is important for RIOT OS beginners to know the recommended parts.
I will buy at86rf233 and mrf24j40 module then try use them.
