Left Frame: common questions
What microcontroller does the Left Frame use?
The Left Frame is built around the ATMEGA16U2-A, from the AVR/Arduino family.
How big is the Left Frame PCB?
The Left Frame measures 29.3 × 187.1 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Left Frame?
120 components, from 22 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 Left Frame design files?
From the FlightDeckDIY/G1000-NXi-Mega 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 Left Frame design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Left Frame 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.
