Avswitch
About the Avswitch PCB
Avswitch is an open source AVR/Arduino PCB design by mmcmaster-au, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 208 × 116 mm, with 286 components from 37 distinct parts.
Its main chip is the ARDUINO_NANO_V3.X, from the AVR/Arduino family. Other key parts include the TPS561243DRLR, LM2611XMF, SRV05-4, AP22816BKEWT and RS8754. By type, the board carries 147 resistors, 81 capacitors, 25 diodes, 15 ICs, 6 connectors and 6 inductors.
It belongs with the power & battery designs in this gallery.
From the project
6 input video switch
The switch will support both component and composite video to provide some flexibility. All of the consoles support composite video. Most of them support component video, though I don't own all the required cables yet. Some (eg. N64 Pal) require a mod to support component video output. Some (eg. PS2) may need a composite connection to enable the the component output.

Avswitch: common questions
What microcontroller does the Avswitch use?
The Avswitch is built around the ARDUINO_NANO_V3.X, from the AVR/Arduino family.
How big is the Avswitch PCB?
The Avswitch measures 208 × 116 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Avswitch?
286 components, from 37 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 Avswitch design files?
From the mmcmaster-au/avswitch 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 Avswitch design in my own project?
Yes, under the terms of its GPL-3.0 license, which mmcmaster-au chose for the repository.
Can I test firmware for the Avswitch without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
