Product introduction:The Longan Nano is a minimalist development board for the GD32VF103C8T6 microcontroller based on the GigaDevice RISC-V 32-bit core. It is convenient for students, engineers and geeks to access the new generation of RISC-V processors and understand their features.The main chip is GD32VF103CBT6, based on the Bumblebee core of the core technology. Support RV32IMAC instruction set and ECLIC fast interrupt function. The core power consumption is only 1/3 of the traditional Cortex-M3.Product parameters Chip built-in 64KB Flash, 20KB SRAM4x universal 16-bit timer,2x basic 16-bit timer,1x advanced 16-bit timerWatchdog, RTC, Systick3xUSART,2xI2C,3xSPI,2x I2S2x CAN,1 xUSBFS (OTG),2 x ADC (10 channel),2 x DAC Longan Nano development board, double-row pin design, 700mil pin spacing, can be directly inserted into the breadboard; onboard 8M passive crystal oscillator, 32.768KHz RTC low-speed crystal oscillator, mini TF card slot, and use Type-C USB interface.
