1 Introduction
GD32107C-EVAL evaluation board uses GD32F107VCT6 as the main controller. As a
complete development platform of GD32F107xx connectivity line powered by ARM®
Cortex™-M3 core, the board supports full range of peripherals. It uses Mini USB interface or
AC/DC adapter as 5V power supply. JTAG, Reset, Boot, User button key, LED, CAN, I2C,
I2S, USART, RTC, EXMC, SPI, USB_OTG, ADC, DAC, Ethernet and Extension Pin are also
included. This document details its hardware schematic and the relevant applications.

3 Getting started
The EVAL Board uses Mini USB connecter to get power, the hardware system power is
+3.3V. A Mini USB cable and a J-Link tool are necessary to down programs. Select the
correct boot mode and then power on, the LED1 will turn on, which indicates the power
supply is ready.
