Useless box: common questions

What microcontroller does the Useless box use?

The Useless box is built around the ATtiny412-SS, from the AVR/Arduino family.

How big is the Useless box PCB?

The Useless box measures 43 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Useless box?

8 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Useless box design files?

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

Can I use the Useless box design in my own project?

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

Can I test firmware for the Useless box 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.
