Conveyor Belt Main Board: common questions
What microcontroller does the Conveyor Belt Main Board use?
The Conveyor Belt Main Board is built around the ATmega328-P, from the AVR/Arduino family.
How big is the Conveyor Belt Main Board?
The Conveyor Belt Main Board measures 94.8 × 117.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Conveyor Belt Main Board?
40 components, from 32 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 Conveyor Belt Main Board design files?
From the Paa-Kwasi-04/Kicad_Projects 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 Conveyor Belt Main Board design in my own project?
The repository has no license, so all rights stay with Paa-Kwasi-04. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Conveyor Belt Main Board 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.
