48 MHz Cortex-M0 with 128 KB Flash — what it covers
The 51 general-purpose I/O pins give you room for parallel interfaces and status lines without needing a port expander.
The peripheral list includes DMA, I²S, POR, PWM, and WDT — enough to handle motor control, audio streaming, or sensor data logging without external glue logic. The 12-bit ADC with 19 channels and the dual 12-bit DAC handle analog sensor inputs and simple waveform generation.
The exposed pad is not listed as a thermal pad, but the LQFP body dissipates well enough for the core's typical current draw. Surface-mount only — no socket option for field swapping without a hot-air station.
It is a current-production STM32F0 series device, widely available through the independent distribution channel.
