DisplayBoard2026: common questions
What microcontroller does the DisplayBoard2026 use?
The DisplayBoard2026 is built around the ATmega328PB-A, from the AVR/Arduino family.
How big is the DisplayBoard2026 PCB?
The DisplayBoard2026 measures 101.9 × 34.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DisplayBoard2026?
78 components, from 33 distinct parts. The full bill of materials is listed on this page.
Where can I download the DisplayBoard2026 design files?
From the KUBTSSAvionics/DisplayBoard2026 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the DisplayBoard2026 design in my own project?
The repository has no license, so all rights stay with KUBTSSAvionics. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the DisplayBoard2026 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.
