VGAutumn

About the VGAutumn PCB

VGAutumn is an open source RP2040/RP2350 PCB design by Alan-GIRAUDON, published on GitHub under the MIT license. It is a 2-layer board measuring 108.5 × 61 mm, with 55 components from 22 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the XC6206P332MR and W25Q128JVS. By type, the board carries 24 resistors, 17 capacitors, 4 switches, 3 ICs, 3 connectors and 3 diodes.

From the project

VGAutumn is a RP2040 VGA joystick PCB. This board allows to play different game using its VGA output and its inputs (joystick, buttons).

- Micro-USB connector to power and program the board - LDO converter, 3V3 for the RP2040, Flash memory, SD card and joystick and LED - 16 MB flash memory - Boot button to put the RP2040 in USB storage mode - VGA connector linked to the RP2040 through a resistor ladder (cheap DAC) - Joystick (vertical, horizontal and pushable) with two buttons - micro-SD card reader - 3 LEDS, White, Blue LED and a Red power LED - Expose the debug pins

VGAutumn: common questions

What microcontroller does the VGAutumn use?

The VGAutumn is built around the RP2040, from the RP2040/RP2350 family.

How big is the VGAutumn PCB?

The VGAutumn measures 108.5 × 61 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the VGAutumn?

55 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the VGAutumn design files?

From the Alan-GIRAUDON/VGAutumn repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the VGAutumn design in my own project?

Yes, under the terms of its MIT license, which Alan-GIRAUDON chose for the repository.

Can I test firmware for the VGAutumn without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
