As the first product in Geehy's new-generation G32F0 motor control MCU platform, the G32F031 features a Cortex-M0+ core at 64MHz, with 64KB Flash and 8KB SRAM. It integrates MULT/DIV/CRC accelerators, a 2 MSPS ADC, op-amps, comparators, and SPI/I2C/U(S)ART interfaces. Suitable for electric tools, vacuum cleaners, high-speed hair dryers, ESCs (automotive, marine, UAV), robotic joints, and low-voltage water pumps.
