Yes it is - the mcu is a stm32wl55jc the moc is a package with extra parts for the radio. This is all in the data sheet see link in original post.

Hi All

I am using an STM32WL5MOC - https://www.st.com/en/product/stm32wl5moc?ecmp=tt9470_gl_link_feb2019&rt=um&id=UM3127

I cannot seem to get the basic wire interface to work. I have the B-WL5M-SUBG1 development board and it has as 5 x I2C componets. https://www.st.com/resource/en/user_manual ...
