Overview
String adapter is an open-source printed circuit board by svanheule, from the svanheule/icecube-display repository on GitHub. It is a 2-layer board of 45 × 29 mm with 5 parts on 6 nets, routed with 22 tracks and 0 vias.
It belongs with the interfaces and adapters boards of this library.
README
README.mdIceCube LED display
This repository contains design documents and firmware source code for a number of LED displays designed to show IceCube event data.
Integration in Steamshovel
A Steamshovel artist was written using pyusb to enable remote rendering. This allows people already familiar with the IceCube offline event viewer to also be quickly able to get a new LED display up and running.
Firmware
The display firmware is written using bare-metal C to provide close integration with the hardware.
Writing a new firmware implementation can take up quite some time, so try to re-use an existing
design if possible. All source code is contained in the firmware directory.
Source code documentation containing guidelines for new display and a short description of existing displays can be compiled using Doxygen:
$ doxygen DoxyfileA copy of the documentation may be found at http://icecube.wisc.edu/~svanheule/icecube-display.
Builds of the microcontroller firmwares can be found at http://icecube.wisc.edu/~svanheule/images. These builds can be used to upgrade existing devices, or provide a starting point for uploading the device EEPROM when using a new device.
Hardware
The hardware directory contains design documents for the displays.
This includes both mechanical documents for the display construction, as well as possible
PCB design documents.

Questions
How big is the String adapter PCB?
It measures 45 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the String adapter use?
5 parts. 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 String adapter KiCad files?
From the svanheule/icecube-display repository on GitHub, at the commit this page was made from: the board is hardware/icecube-modular/pcb/string_adapter/string_adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the String adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask svanheule before reusing the design.
