From the project

Tatung Einstein TC-01

This isn't particularly serious and it's going to have some haters, so an explanation is needed first off. The idea was to do an as simple as possible Einstein - bits removed or substituted - to fit on a mini-ITX board (170x170mm) as 5V only to prove some schematics. It's cheap to make, being small and the VDP being substituted, the only particularly expensive chip being the WD1770.

EinsteinCE: common questions

What microcontroller does the EinsteinCE use?

The EinsteinCE is built around the ATMEGA328, from the AVR/Arduino family.

How big is the EinsteinCE PCB?

The EinsteinCE measures 170 × 170.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EinsteinCE?

153 components, from 78 distinct parts. The full bill of materials is listed on this page.

Where can I download the EinsteinCE design files?

From the Board-Folk/Einstein-TC-01 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the EinsteinCE design in my own project?

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

Can I test firmware for the EinsteinCE 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.
