MicArrayFinal: common questions

What microcontroller does the MicArrayFinal use?

The MicArrayFinal is built around the ArduinoLike, from the AVR/Arduino family.

How big is the MicArrayFinal PCB?

The MicArrayFinal measures 183.4 × 183.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MicArrayFinal?

41 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the MicArrayFinal design files?

From the dylanzodrow/Aerial_Drone_Tracking repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the MicArrayFinal design in my own project?

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

Can I test firmware for the MicArrayFinal 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.
