VGA Proto: common questions

What microcontroller does the VGA Proto use?

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

How big is the VGA Proto PCB?

The VGA Proto measures 37.1 × 63.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the VGA Proto?

62 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the VGA Proto design files?

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

Can I use the VGA Proto design in my own project?

Yes, under the terms of its MIT license, which baldengineer chose for the repository.

Can I test firmware for the VGA Proto 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.
