About the Microcontroller PCB

Microcontroller is an open source AVR/Arduino PCB design by AUV-IITK, published on GitHub. It is a 2-layer board measuring 65.4 × 46.4 mm, with 47 components from 21 distinct parts.

Its main chip is the ATmega2560-16AU, from the AVR/Arduino family. Other key parts include the ATmega8U2-MU. By type, the board carries 13 resistors, 12 capacitors, 3 diodes, 2 ICs, 2 connectors and 1 fuse.

From the project

The MicrocontrollerPCB section contains the scematic and the PCB layout done in KICAD and would be updated from time to time.

Microcontroller: common questions

What microcontroller does the Microcontroller use?

The Microcontroller is built around the ATmega2560-16AU, from the AVR/Arduino family.

How big is the Microcontroller PCB?

The Microcontroller measures 65.4 × 46.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Microcontroller?

47 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Microcontroller design files?

From the AUV-IITK/electrical-systems repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Microcontroller design in my own project?

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

Can I test firmware for the Microcontroller 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.
