About the KiCad-LarsonScanner PCB

KiCad-LarsonScanner is an open source AVR/Arduino PCB design by kaderud, published on GitHub under the Custom license license. It is a 2-layer board measuring 174.4 × 60.3 mm, with 63 components from 13 distinct parts.

Its main chip is the ATmega328P-PU, from the AVR/Arduino family. Other key parts include the LM7805 and 74HC595. By type, the board carries 26 diodes, 26 resistors, 5 ICs, 4 capacitors, 1 crystal and 1 connector.

From the project

KiCad project for a Larson Scanner PCB

These are the source files for the KiCad project "Larson Scanner"

If you want to make one of these for yourself you can use this design as it is or alter it and make it better.

The Gerber files in the Production directory are the identical files used to produce the PCBs.

Here are some images of the v1.0 release board:

KiCad-LarsonScanner: common questions

What microcontroller does the KiCad-LarsonScanner use?

The KiCad-LarsonScanner is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the KiCad-LarsonScanner PCB?

The KiCad-LarsonScanner measures 174.4 × 60.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KiCad-LarsonScanner?

63 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the KiCad-LarsonScanner design files?

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

Can I use the KiCad-LarsonScanner design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the KiCad-LarsonScanner 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.
