[ngodoanvan]

Hi,

Can I use STM32WL_UFQFPN48_Reference_Design_+22dBm_490MHz.PDF reference schematic file (attached) in en.STM32WL_Reference_Board_MB1720-XO_IOs_Shield to design my project +22dBm - 433MHz ????

Hello @Ngô Vạn​ ,

You can find the last update of your board schematics here !

Yes you can use this schematic to communicate at 433MHz as this is considered to be part of the Lower Band.

Hello,

You can refer to the datasheet here, on the section 7, you can find your package with the model of your board.

Here, you have a UFQFPN48 so you can use this design

Hi,

In MB1720 reference, the C19 capacitor and C25 capacitor manufacturer part number are GRM1555C1HR68WB01D. This MPN seems wrong because I can't find it in Murata. Please review for me.

Thanks
