LPA-hardware: common questions

What microcontroller does the LPA-hardware use?

The LPA-hardware is built around the ATMEGA328-A, from the AVR/Arduino family.

How big is the LPA-hardware PCB?

The LPA-hardware measures 143 × 74 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LPA-hardware?

81 components, from 19 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 LPA-hardware design files?

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

Can I use the LPA-hardware design in my own project?

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

Can I test firmware for the LPA-hardware 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.
