About the PCB Design DD

PCB Design DD is an open source AVR/Arduino PCB design by Vishwakarma10036, published on GitHub. It is a 2-layer board measuring 60 × 60 mm, with 9 components from 9 distinct parts.

Its main chip is the ATtiny85V-10P, from the AVR/Arduino family. By type, the board carries 4 resistors, 1 IC, 1 battery holder, 1 microphone, 1 switch and 1 diode.

From the project

This repository contains the complete design workflow of a Digital Diya PCB developed using KiCad. It includes circuit schematics, PCB layout, Gerber files for fabrication, 3D board models, and final hardware outputs.

Digital Diya (Sound + Light Activated LED) using ATtiny85 – PCB Designed in KiCad 9.0

This project is a Digital Diya PCB designed in KiCad 9.0, which works like a smart diya/light.

It uses: - LDR07 to detect light/dark conditions - Condenser Microphone to detect sound (clap/blow) - ATtiny85-10P as the controller - LED as the diya light output - Battery cell (3.3V) for portable power - SPDT switch for ON/OFF control

PCB Design DD: common questions

What microcontroller does the PCB Design DD use?

The PCB Design DD is built around the ATtiny85V-10P, from the AVR/Arduino family.

How big is the PCB Design DD?

The PCB Design DD measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB Design DD?

9 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB Design DD design files?

From the Vishwakarma10036/PCB_Design_DD repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB Design DD design in my own project?

The repository has no license, so all rights stay with Vishwakarma10036. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PCB Design DD 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.
