README
README.mdHackpack v4 Hardware Collateral
This repo contains all of the hardware collateral you need to create a device functionally equivalent to the Hackpack v4 from Twilio's SIGNAL 2018 Conference.
See also our blog post announcing this repository.
Hardware Collateral
Everything you need to build a badge PCB can be found in the KiCad folder. The Hackpack v4 was designed using KiCad major version 5. Download a copy here.
You'll also need to purchase a Raspberry Pi Zero W and a 8GB or larger MicroSD card to use the board.
Don't want to use KiCad?
You can find pre-generated Gerbers in the KiCad/Gerbers directory. Use them at your PCB house of choice to manufacture a board.
We've also included the bill of materials and schematic in generic formats.
Firmware
You can find firmware either through our repository (start with a vanilla Raspbian installation) or pre-imaged on the Hackpack v4 site.
Special Assembly Instructions
The Bill of Materials can be found in the KiCad directory. Some parts cannot be found at the normal supply sources and are best sourced from Amazon.
The SMD Grove header was impossible to find in the US at the time this repo was released. Use a through hole Grove header and bend the pins with pliers for an excellent substitute.
The Amazon ILI9341 screen linked in the special assembly instructions has an inverted touchscreen to the one we used at the show. To fix the touchscreen driver you'll need to set flags:
echo "100" > /home/pi/.ili9341_touch.conf

Questions
How big is the HackPackv4 PCB?
It measures 93.5 × 149.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HackPackv4 use?
44 parts, built around the MCP3008-I/P, WS2812B, NCE3407A and MMSD4148. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the HackPackv4 KiCad files?
From the twilio/hackpack-v4-hardware repository on GitHub, at the commit this page was made from: the board is KiCad/HackPackv4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HackPackv4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask twilio before reusing the design.
