Sipeed Longan Nano is a development board based on the GD32VF103CBT6 MCU with RISC-V 32-bit core by GigaDevice. It is convenient for students, engineers, and geek enthusiasts to tinker with the new-generation RISC-V processors. Longan Nano comes with a 0.96inch 160x80 IPS RGB LCD.

GD32VF103CBT6 is a Bumblebee core, based on Nuclei System Technology. Support RV32IMAC instruction set and ECLIC fast interrupt function. Core power consumption is only 1/3 of that of traditional Cortex-M3.  

Longan Nano development board has a double-row pin layout design with a needle spacing of 700 mil, which can be inserted directly into a breadboard. Also, it has an on-board 8M passive crystal oscillator, 32.768 kHz RTC low-speed crystal oscillator, Mini TF slot, and uses Type-C USB interface. 

Longan Nano supports multiple download methods: USB DFU download, UART ISP download, JTAG download. In the USB DFU download mode, you only need a USB Type-C cable to download the program to the development board. At the same time, Longan Nano supports the standard JTAG interface, which can be debugged online using the in-store RISC-V debugger or any JTAG-enabled debugger such as J-Link. 

Meanwhile, Sipeed has adapted the PlatformIO IDE for the Longan Nano development board, which can be visually developed on multiple platforms such as Windows/Linux:
