TFRAS TOP: common questions

What microcontroller does the TFRAS TOP use?

The TFRAS TOP is built around the ATmega328PB-MU, from the AVR/Arduino family.

How big is the TFRAS TOP PCB?

The TFRAS TOP measures 24 × 24 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TFRAS TOP?

27 components, from 15 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 TFRAS TOP design files?

From the geus-clan/TFRAS repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the TFRAS TOP design in my own project?

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

Can I test firmware for the TFRAS TOP 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.
