Frequently asked questions
What is the closest functional alternative to STM32L031C4T6?
The STM32L151CBU6A is a step up — it uses a Cortex-M3 core at the same 32 MHz, but offers more memory and adds USB connectivity. It is not pin-compatible (different package), so a board spin is required to migrate.
