Hello @Bonnie ,

You can refer to the Getting started with STM32L0xx hardware development in section in section 6-Reference design

where you can find some useful details about the implementation of the STM32L0 series MCUs.

You can also inspire from NUCLEO-L073RZ in this link .

Start by reviewing the Data Sheet, paying special attention to power, capacitors, BOOTx and NRST. Make sure to escape a means of programming/debugging via SWDIO/SWCLK, and understand the system loader via AN2606

Most of ST's boards have schematics, and these can be found under the "CAD Resources" tab on the respective product pages.

Absolutely!

@Bonnie  Best to also include NRST - that can get you out of some holes where the debugger can't access the Target...

Are you familiar with designing for other microcontrollers? Much of it is common...
