Main 2.4: common questions

What microcontroller does the Main 2.4 use?

The Main 2.4 is built around the A000067, from the AVR/Arduino family.

How big is the Main 2.4 PCB?

The Main 2.4 measures 214.9 × 206.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main 2.4?

40 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Main 2.4 design files?

From the eesakiii/SilverbackPCBs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Main 2.4 design in my own project?

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

Can I test firmware for the Main 2.4 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.
