SPIDER Automation NUCLEO-G474RE Nucleo-64 Development Board | STM32G474RE MCU
Description
SPIDER Automation STMicroelectronics NUCLEO-G474RE Nucleo-64 Development Board provides an affordable, flexible way for engineers and makers to build advanced prototypes and test new concepts using STMicroelectronics’ mixed-signal STM32G4 series. Driven by the STM32G474RET6U 32-bit ARM Cortex-M4 RISC processor with hardware FPU and DSP instructions, this board is specifically optimized for digital power conversion, motor control, lighting, and industrial applications requiring precise timing and analog feedback.
Equipped with Arduino Uno V3 connectors and ST morpho extension pin headers, the NUCLEO-G474RE offers total hardware flexibility and complete access to all microcontroller I/Os. It features an onboard ST-LINK debugger/programmer, an external SMPS to significantly reduce power consumption in run mode, and a 32.768 kHz crystal for real-time clock operations. Fully supported by STM32CubeIDE, Keil, IAR, and GCC-based toolchains, it delivers an exceptional environment for high-performance embedded development.
