The STM32G031K6U6 is a 32-bit ARM Cortex-M0+ microcontroller from ST's STM32G0 series, clocked at 64 MHz. The 18-channel 12-bit SAR ADC covers a dense sensor array — think eight analog inputs for a temperature multiplexer plus a few for voltage and current monitoring — without needing an external MUX.
The 64 MHz Cortex-M0+ handles a control loop with margin for background communications and ADC reads. If the firmware fits in 32 KB, this part is the right BOM fit.
