This repository contains the KiCad design for Azalea, also known as GreatFET One. The design requires:

https://github.com/greatscottgadgets/gsg-kicad-lib

If you are using git, the preferred way to install gsg-kicad-lib is to use the submodule:

git submodule init && git submodule update

Overview

Also known as GreatFET One, Azalea is the main board of the GreatFET project.

Azalea is a peripheral interface tool. By adding expansion boards called "neighbors", you can turn Azalea into a USB peripheral that does almost anything.

Features:

• LPC4330 microcontroller (U1)
• Hi-Speed USB port (USB0) for connection to a host computer
• Expansion interface (J1 and J2) of 80 pins (2 female headers with 2 rows of 20 pins)
• Bonus row of 20 male pins (J7)
• 4 indicator LEDs
• 2 buttons, primarily for development (DFU and RESET, just like HackRF One)
• Full Speed USB port (USB1) for connection to a target (for Facedancer)
• Power switching for use of USB1 as either host or device
• 3.3 V regulator that can supply some power to neighbors
• 2 MB flash memory
• Unpopulated Cortex Debug Header (J5) for JTAG or SWD

Except where noted below, all pins on expansion ports use 3.3 V I/O voltage.

The vector graphic file provided in this repo was created with Inkscape.

The black lines are the edge cuts. The blue lines are cut outs. The red lines are optional and should be lightly etched if they are used. The red lines are meant to be used to help count holes in the headers.

The BOM

• 4 x 4.5 mm OD Hex Standoffs (Female-Female) / M3-0.5 x 6 mm / Aluminum
• 4 x 4.5 mm OD Hex Standoffs (Female-Female) / M3-0.5 x 5 mm / Aluminum
• 4 x M3-0.5 x 12 mm / Phillips Pan Head Machine Screw
• 4 x M3-0.5 x 5 mm / Phillips Pan Head Machine Screw

Optional:

• 4 (per neighbor) x 4.5 mm OD Hex Standoffs (Male-Female) / M3-0.5 x 11 mm / Aluminum

These standoffs are to be used if a neighbor is stacked on your GreatFET One and you want your case to be stacked above that neighbor.
