Tito: common questions

What microcontroller does the Tito use?

The Tito is built around the ATMEGA88A-A, from the AVR/Arduino family.

How big is the Tito PCB?

The Tito measures 65 × 107.5 mm and is 1.6002 mm thick.

How many components are on the Tito?

85 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tito design files?

From the cdrfiuba/tito repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Tito design in my own project?

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

Can I test firmware for the Tito 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.
