About the SuborFpga PCB

SuborFpga is an open source PCB design by 2bitsin, published on GitHub. It is a 2-layer board measuring 97.8 × 108 mm, with 39 components from 21 distinct parts.

Other key parts include the ADV7125KSTZ50, CS4334-KSZ and AS6C4008-55PCN. By type, the board carries 14 resistors, 12 capacitors, 6 ICs and 2 connectors.

It belongs with the audio, retro computing and dev boards & breakouts designs in this gallery.

From the project

NES in SystemVerilog on a QMTech Cyclone V FPGA, plus a VGA/audio/gamepad daughter board

A KiCad board that plugs onto the QMTech Cyclone V core board (5CEFA5F23) through its two 2×32 pin headers. It gives the FPGA everything a NES needs to talk to the outside world.

Jumper points let you route the audio through the VGA connector instead.
