About the Arduino delay PCB

Arduino delay is an open source AVR/Arduino PCB design by gridbugs, published on GitHub under the MIT license. It is a 2-layer board measuring 55.1 × 151.8 mm, with 47 components from 32 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. Other key parts include the TL074. By type, the board carries 13 resistors, 10 connectors, 7 capacitors, 3 switches, 2 ICs and 2 diodes.

From the project

A modular synthesizer, where modules are designed as close to bare PCBs as is practical/safe. This is the spiritual successor to the briefcase modular synthesizer.

Arduino delay: common questions

What microcontroller does the Arduino delay use?

The Arduino delay is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Arduino delay PCB?

The Arduino delay measures 55.1 × 151.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino delay?

47 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Arduino delay design files?

From the gridbugs/modular2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Arduino delay design in my own project?

Yes, under the terms of its MIT license, which gridbugs chose for the repository.

Can I test firmware for the Arduino delay 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.
