About the DLC PCB

DLC is an open source AVR/Arduino PCB design by gokul-rm, published on GitHub. It is a 2-layer board measuring 42.5 × 30.5 mm, with 13 components from 8 distinct parts.

Its main chip is the ATtiny85-20S, from the AVR/Arduino family. Other key parts include the LM1117DT-5.0. By type, the board carries 5 connectors, 3 resistors, 2 ICs, 2 capacitors and 1 diode.

It belongs with the power & battery and sensors designs in this gallery.

From the project

2. Open the project in KiCad: - Open KiCad and load the required .pro file. - Access the schematic editor and PCB layout as needed. 3. Generate Gerber files for manufacturing: - Use KiCad's "Plot" function to export Gerber files.

DLC: common questions

What microcontroller does the DLC use?

The DLC is built around the ATtiny85-20S, from the AVR/Arduino family.

How big is the DLC PCB?

The DLC measures 42.5 × 30.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DLC?

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

Where can I download the DLC design files?

From the gokul-rm/PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DLC design in my own project?

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

Can I test firmware for the DLC 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.
