STM32 NUCLEO-G431RB - STM32G431RB Arm Cortex M4

STM32 Nucleo module with 32-bit STM32G431RB microcontroller, which is equipped with 170 MHz Arm Cortex-M4 core, 128 kB Flash memory and 32 kB SRAM. The board belongs to Nucleo-64 family, which means that it is not onlycompatible with mbed platform, but also has connectors for interfacing overlays designed to work with Arduino Uno and ST Morpho pins, which give access to all microcontroller GPIO pins. STM32 Nucleo-G431RE module is compatible with many Integrated Development Environments (IDE), among them we can mention IAR Embedded Workbench, MDK-ARM and STM32CubeIDE. The device is equipped with ST-LINK debugger / programmer.

The board is equipped with connectors overlapping with Arduino Uno Rev3 pin layout, such solution allows direct connection ofdedicated Shield extensions.
