Sipeed Longan Nano v1.1- RISC-V GD32VF103CBT6 Development Board

SKU: SS102991574 Brand: Seeed Studio

As an updated version to Sipeed Longan Nano, the Sipeed Longan Nano V1.1 development board has been modified the pin definitions of headers and board outline by us. Also, for looking tidy, we gifted it a new shell. The board is based on GD32VF103CBT6 MCU with the RISC-V 32-bit core of GigaDevice.

Sipeed Longan Nano v1.1 is an updated development board based on the GD32VF103CBT6 MCU chip which has built-in 128KB Flash, 32KB SRAM. It is convenient for students, engineers, and geek enthusiasts to tinker with the new-generation RISC-V processors. GD32VF103CBT6 is a Bumblebee core, based on Nuclei System Technology supporting RV32IMAC instruction set and ECLIC fast interrupt function. Meanwhile, it costs only 1/3 of that of traditional Cortex-M3.

There can be multiple timer modules on the given device, e.g., four general-purpose 16-bit timers, two basic 16-bit timers, and one advanced 16-bit timer. More specifically, it has a watchdog timer to monitor the main program, an RTC(Real-time clock) to provide stable clock signals, and a SysTick(System tick timer) to maintain the main system working.

Longan Nano v1.1 development board has 28 GPIOs connected to the row pins which is so convenient that it can support connecting lots of devices. And it can be reset anytime by the Reset Button and the BOOT button. 160x80 RGB IPS LCD can be connected to its SPI screen interface. Also, it has an on-board 8M passive crystal oscillator, 32.768 kHz RTC low-speed crystal oscillator, TF Card Holder, 1 RGB LED, and uses a Type-C USB interface.

Longan Nano v1.1 supports multiple download methods, e.g., USB DFU download, UART ISP download, and JTAG download. By USB DFU download mode, you only need a USB Type-C cable to download the program to the development board. Longan Nano v1.1 supports the standard JTAG interface, which means it can debug online using the in-store RISC-V debugger or any JTAG-enabled debugger such as J-Link.

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