Seeed Studio GD32 RISC-V Dev Board is based on GD32VF103VBT6 MCU which can run at up to 108MHz. GD32VF103 is a 32-bit general-purpose microcontroller based on the RISC-V core. It provides128 KB on-chip Flash memory, 32 KB SRAM memory, 5x U(S)ART, 2 x I2C, 3 x SPI, 2 x I2S, 2 x CAN2.0, 1 x USBFS.
With the onboard 8MB flash and 256Byte EEPROM, you can implement more complex applications. The development board includes an LCD interfcae, a type c USB port, a microSD card slot, two user buttons, and three user LEDs.
Seeed Studio supports the PlatformIO IDE and the Arduino framework for GD32. You can either develop with the Arduino API you are familiar with or copy your existing Arduino applications.
