Lcd monitor: common questions

What microcontroller does the Lcd monitor use?

The Lcd monitor is built around the ATmega328PB-AU, from the AVR/Arduino family.

How big is the Lcd monitor PCB?

The Lcd monitor measures 75.4 × 39.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lcd monitor?

74 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lcd monitor design files?

From the lcdporto/lcd-monitor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Lcd monitor design in my own project?

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

Can I test firmware for the Lcd monitor 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.
