1 Introduction
GD32103E-EVAL evaluation board uses GD32F103ZET6 as the main controller. As a
complete development platform of GD32F103xx 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, SDIO, RTC,
EXMC, SPI, USB, ADC, DAC and Extension Pin are also included. This document details its
hardware schematic and the relevant applications.
