Product description: Sipeed Longan Nano RISC-V development board GD32VF103CBT6 - Seeedstudio 114992425
Sipeed Longan Nanodevelopment boardfrom Seeedstudio. It usesGD32VF103CBT6microcontroller whichwas created in cooperation between GigaDevice and Nuclei System Technology. It is based on the Bumblebee core, which runs the open source RISC-V instruction set. The board can be programmed via USB DFU, UART ISP and JTAG. It supports communication interfaces: 3 x USART, 2 x I2C, 3 x SPI, 2 x I2S, 2 x CAN, 1 x USBFS (OTG) and USB type C. It also features an IPS LCDdisplaywith a resolution of160 x 80 pxand a diagonal of0.96". The board is designed for students, engineers and enthusiasts working with next generation RISC-V processors.
The Sipeed Longan Nano also includes a 0.96" diagonal LCD display.
