8bitdvco: common questions

What microcontroller does the 8bitdvco use?

The 8bitdvco is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the 8bitdvco PCB?

The 8bitdvco measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 8bitdvco?

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

Where can I download the 8bitdvco design files?

From the eblade/synth repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 8bitdvco design in my own project?

The repository has no license, so all rights stay with eblade. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 8bitdvco 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.
