Longan Nano is a development board based on GD32VF103CBT6 MCU with RISC-V 32-bit core of GigaDevice. Longan Nano sold by Seeed comes with a 0.96inch 160x80 IPS RGB LCD and an acrylic transparent case.

Sipeed Longan Nano is a development board based on GD32VF103CBT6 MCU with RISC-V 32-bit core of GigaDevice. It is convenient for students, engineers and geek enthusiasts to contact the new-generation RISC-V processor. Longan Nano sold by Seeed comes with a 0.96inch 160x80 IPS RGB LCD and an acrylic transparent case.

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, double-row pin layout design, needle spacing 700 mil, can be inserted directly into breadboard; on-board 8M passive crystal oscillator, 32.768 KHz RTC low-speed crystal oscillator, Mini TF slot, and use 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:
