Development board to test the STM32G431. This microcontroller has some useful DSP functions and peripherals that I was eyeing for a different project. Ideally this development board will be used to experiment with the onboard op-amps, comparators, ADC, and DAC of the microcontroller.

A text dump of some of the datasheet features is shown below…

Core: Arm® 32-bit Cortex®-M4 CPU with FPU, Adaptive real-time accelerator (ART Accelerator) allowing 0-wait-state execution from Flash memory, frequency up to 170 MHz with 213 DMIPS, MPU, DSP instructions

2 x ADCs 0.25 µs (up to 23 channels). Resolution up to 16-bit with hardware oversampling, 0 to 3.6 V conversion range

4 x 12-bit DAC channels
- 2 x buffered external channels 1 MSPS
- 2 x unbuffered internal channels 15 MSPS

4 x ultra-fast rail-to-rail analog comparators
