Sipeed Longan Nano – RISC-V Development Board with RGB Display

Item Type: Development Board Model Series: Sipeed Longan CPU: GD32VF103CBT6 (RISC-V 32-bit core)

🧠 Overview:

The Sipeed Longan Nano is a compact and powerful RISC-V development board based on the GD32VF103CBT6 MCU with a 32-bit RISC-V core by GigaDevice. It’s ideal for students, embedded engineers, and hardware hackers looking to explore the future of open-source CPU architectures.

It features a 0.96" 160×80 IPS RGB LCD, acrylic transparent case, and a breadboard-friendly layout, making it the perfect platform to get hands-on with RISC-V.

🧾 Description:

Powered by the Bumblebee core (Nuclei System Technology), the Longan Nano supports the RV32IMAC instruction set and ECLIC fast interrupts, while consuming only 1/3 the power of Cortex-M3.

Its dual-row 700 mil pin spacing allows direct insertion into breadboards. The board includes:

• 8MHz passive crystal oscillator
