The Heijin AX7103 FPGA development platform user manual details hardware specs, interfaces, power requirements, and usage guidelines.
The AX7103 is a high‑end FPGA development platform that follows a core‑board plus expansion‑board architecture. The core board integrates a Xilinx Artix‑7 XC7A100T FPGA, two DDR3 memory chips (total 8 Gbit) and a 128 Mb QSPI Flash, providing up to 25 Gb/s bandwidth between the FPGA and DDR3. The board is designed for fast data processing, video handling and industrial control applications.
The platform offers a rich set of peripherals: a PCIe x4 Gen2 slot, two Gigabit Ethernet ports, HDMI output and input (1080p @ 60 Hz), a USB‑UART interface, a micro‑SD card slot, EEPROM, multiple 40‑pin expansion connectors, LEDs, and user buttons. Power is supplied via a DC 12 V input, PCIe power or ATX supply, and the board includes on‑board DC‑DC converters to generate the required 5 V, 3.3 V, 1.8 V and 1.2 V rails. This manual is written in Chinese.
