Logic: common questions

What microcontroller does the Logic use?

The Logic is built around the FS1403-5000-AL, from the AVR/Arduino family.

How big is the Logic PCB?

The Logic measures 65.6 × 64.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Logic?

66 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Logic design files?

From the try-except/TitoSync repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Logic design in my own project?

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

Can I test firmware for the Logic 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.
