Simple i2c screen: common questions
What microcontroller does the Simple i2c screen use?
The Simple i2c screen is built around the ATmega328P-AU, from the AVR/Arduino family.
How big is the Simple i2c screen PCB?
The Simple i2c screen measures 100 × 73.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Simple i2c screen?
34 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the Simple i2c screen design files?
From the Hackuarium/simple-i2c-screen repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Simple i2c screen design in my own project?
The repository has no license, so all rights stay with Hackuarium. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Simple i2c screen 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.
