About the Bartender arduino hat

Bartender arduino hat is an open source AVR/Arduino PCB design by dburnsii, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 21.5 × 19 mm, with 4 components from 4 distinct parts.

Its main chip is the Arduino_Left, from the AVR/Arduino family.

It belongs with the robotics & motion and dev boards & breakouts designs in this gallery.

The intelligent, robotic, drink making machine of the future!

Here you'll find all the hardware you'll need to assemble your own The Bartender. There are quite a few parts you'll need, and most of them can be purchased for very cheap from eBay, however you'll likely end up with more parts than you'll need for most things. As this project gains popularity, kits may become available to make getting started a lot easier.

The list of cuts you'll need to make to the single 4'x8' sheet of plywood are available in .csv format. My current favorite tool for this purpose is CutListOptimizer. It isn't a FOSS tool, but you should only need to use it once or twice…

Bartender arduino hat: common questions

What microcontroller does the Bartender arduino hat use?

The Bartender arduino hat is built around the Arduino_Left, from the AVR/Arduino family.

How big is the Bartender arduino hat?

The Bartender arduino hat measures 21.5 × 19 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bartender arduino hat?

4 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bartender arduino hat design files?

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

Can I use the Bartender arduino hat design in my own project?

Yes, under the terms of its GPL-2.0 license, which dburnsii chose for the repository.

Can I test firmware for the Bartender arduino hat 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.
