Holter is an open-source printed circuit board by peterisza, from the peterisza/mobilecg repository on GitHub. It is a 6-layer board of 30 × 48 mm with 231 parts on 176 nets, routed with 2,956 tracks and 352 vias.
It is built around the OPA379M/TR, TLV61220DBV and TS5A3159DBV, with the TXB0106PW, LIS2DH12 and USBULC6-2M6 among its other parts. Its parts include 106 capacitors, 56 resistors, 28 ICs, 6 connectors and 5 inductors. It belongs with the STM32 boards of this library.

NOTE: this is only a preliminary release. It contains known bugs, but its main structure will remain the same. There is no stable branch yet. Development occours on master. When a stable software is released, it will be split to separate stable and development branches.

└───CardECG - Toy, credit card ECG project.MobilECG is not publicly available yet. In order to sell a medical device, certification is needed. We are working hard to bring MobilECG to the users as soon as possible.
However you can still build one yourself. If you want to build it, feel free to do so. Contact us in case of any problems. There will be soon a technical blog where you will be able to find instructions on bulding one yourself.
The whole project is built using free or open source tools. The hardware is designed in KiCAD (http://kicad-pcb.org), the firmware compiles with ARM GCC (you can find binaries here: https://launchpad.net/gcc-arm-embedded), CAD files are designed with OpenSCAD (http://www.openscad.org) and 3D printed using MatterControl on a Prusa i3. The development occours on Mac OS X and Linux, building was never tested on Microsoft Windows (and we are not interested in making this software build on Windows except the Windows client app that will be written).
If you know a doctor or someone with a heart condition, please let them know about our project. Their subscription will help us find investment.
If you are a business angel or an investor, please contact us.

KiCad project to create a custom USB-C key with mass storage and a microSD connector. Find all the KiCad schematics and layout files.
It measures 30 × 48 mm and has 6 copper layers, 1.6 mm thick.
231 parts, built around the OPA379M/TR, TLV61220DBV, TS5A3159DBV and TXB0106PW. 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.
From the peterisza/mobilecg repository on GitHub, at the commit this page was made from: the board is Hardware/holter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask peterisza before reusing the design.
