Mega shield: common questions
What microcontroller does the Mega shield use?
The Mega shield is built around the Arduino_Mega2560_Shield, from the AVR/Arduino family.
How big is the Mega shield?
The Mega shield measures 121.9 × 83.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mega shield?
31 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mega shield design files?
From the rashikshrestha/chatpate-circuits repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Mega shield design in my own project?
The repository has no license, so all rights stay with rashikshrestha. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mega shield 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.
