About the Board

Board is an open source FPGA PCB design by pinguz97, published on GitHub under the CERN-OHL-S-2.0 license. It is a 8-layer board measuring 50 × 42 mm, with 267 components from 44 distinct parts.

Its main chip is the XC7Z020-CLG484, from the FPGA family. Other key parts include the MT41K256M16TW-107_P, RTL8211F, MPM3834, USB3318 and IS21ES08G. By type, the board carries 137 capacitors, 100 resistors, 13 ICs, 9 inductors, 3 crystals and 3 connectors.

Board: common questions

What microcontroller does the Board use?

The Board is built around the XC7Z020-CLG484, from the FPGA family.

How big is the Board?

The Board measures 50 × 42 mm, has 8 copper layers and is 1.2396 mm thick.

How many components are on the Board?

267 components, from 44 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Board design files?

From the pinguz97/Zynq-SoM repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Board design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which pinguz97 chose for the repository.

Can I test firmware for the Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
