QD_GY_V1.2 Kintex-7 Development Board Specs

Found for sale on various sites like AliExpress & eBay for under US$100.

What's cool about this chip: Can be used without a license in Vivado BASIC which is free.

Specs

• AMD / Xilinx Kintex-7 FPGA: xc7k325tffg676-2I
• TPS53355DQPR TI Buck DC-DC Voltage Regulator
• ADP1823 Dual-Channel Synchronous Step-Down DC-DC Controller
• Delta sn46-0r4 $0.4uH High-Current Power Inductor
• XIA OE 50.000MHz Crystal Oscillator
• 14 GPIO ports exposed
• 4 addressable LEDs
• 1 addressable button (P6 address invalid - haven't tried to get it working)
• Standard 2mm JTAG
• 2 2x17 headers
• Requires 12v, 3.3v & 1.8v power

Special Concerns:

1. Vivado requires setting environment variable XIL_IMPACT_SKIPIDCODECHECK=1
2. System clk pin is AC23 NOT B26!!!
3. Solder pads for power accessible from top
4. Minor water damage & some poor solder joints
