LoopingLouino: common questions

What microcontroller does the LoopingLouino use?

The LoopingLouino is built around the ATMEGA328P-A, from the AVR/Arduino family.

How big is the LoopingLouino PCB?

The LoopingLouino measures 50 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LoopingLouino?

58 components, from 34 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 LoopingLouino design files?

From the RedlabsDE/LoopingLouino 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 LoopingLouino design in my own project?

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

Can I test firmware for the LoopingLouino 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.
