0693W00000WJpUrQAL.pngHi team,

I used STM32WB15CCU6 in my project for Voltage and sensing. I already used all analog pin for sensing.

I need one SPI and one UART communications channels.

Can you please suggest which pins can I used for SPI and UART.

I request please share the schematic or pin mapping details.

Thanks & Regards
