المواصفات
GD32F103CBT6 is a mainstream 32-bit general-purpose microcontroller developed by GigaDevice Semiconductor, built around ARM Cortex-M3 core with maximum 108MHz operating frequency. It delivers higher execution efficiency and lower power consumption compared to equivalent Cortex-M3 MCUs on the market, featuring abundant built-in peripherals and pin-compatible alternative to STM32F103C8T6 for cost-sensitive embedded projectsGigaDevice.
👉 It is not high-end GD32F105/F107 series with Ethernet or USB OTG function, nor low-density GD32F101 value-line without CAN/USB. This mid-range LQFP48 model balances memory capacity, communication interfaces and PCB footprint, ideal for industrial control, USB data acquisition and CAN bus networking equipment.
