LFR ATMega4808 V2: common questions

What microcontroller does the LFR ATMega4808 V2 use?

The LFR ATMega4808 V2 is built around the ATmega4808-A, from the AVR/Arduino family.

How big is the LFR ATMega4808 V2 PCB?

The LFR ATMega4808 V2 measures 70 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LFR ATMega4808 V2?

64 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the LFR ATMega4808 V2 design files?

From the peterladur/ENMT221-PCB-Design repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LFR ATMega4808 V2 design in my own project?

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

Can I test firmware for the LFR ATMega4808 V2 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.
