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.

Regards

Louis

Hi, can I use this design for STM32WLE5CBU6 ? Thank for your answer.

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
