LED Nametag: common questions

What microcontroller does the LED Nametag use?

The LED Nametag is built around the ATtiny85-20P, from the AVR/Arduino family.

How big is the LED Nametag PCB?

The LED Nametag measures 100 × 64 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LED Nametag?

28 components, from 13 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 LED Nametag design files?

From the LyricSantana/LED_Nametag 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 LED Nametag design in my own project?

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

Can I test firmware for the LED Nametag 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.
