The GD32F103VET6 is a 32-bit high-performance microcontroller based on the ARM Cortex-M3 core, manufactured by GigaDevice. It operates at a maximum frequency of 108MHz and features 512KB Flash and 64KB SRAM, housed in an LQFP-100 package. This device offers a rich set of communication interfaces (including 5 USARTs, 3 SPIs, 2 I²Cs, 1 CAN, and USB) and analog peripherals (3 × 12-bit ADCs, 2 × 12-bit DACs), and supports FSMC for external memory expansion. It is pin-compatible with the STM32F103 series, but software is not directly compatible. The GD32F103VET6 is suitable for cost-sensitive applications such as industrial control, IoT, and consumer electronics.
