Overview
Z2breakout is an open-source printed circuit board by projectgus, from the projectgus/z2breakout repository on GitHub. It is a 2-layer board of 44.5 × 26 mm with 15 parts on 32 nets, routed with 764 tracks and 105 vias.
It is built around the TPS61240DRV. Its parts include 4 connectors, 2 capacitors, 2 resistors, 1 switch and 1 inductor. It belongs with the interfaces and adapters and microcontroller boards boards of this library.
Main components
1README
README.mdThis is an abandoned alpha-quality design at this point, unless someone wants to pick it up. I built some prototypes in late 2013 and the USB connector & boost converter are verified, but there's some known problems with the connector pinout and the silkscreen is also pretty messy, the whole board probably needs to grow for more labelling space.
Z2 Breakout module
A breakout board for the "ZipIt Z2" dock connector. Alpha-quality at the moment.
Design files created with Kicad 2013-Mar-13-testing (this version or newer is probably required.)
Breaks out dock connector to provide:
- USB A & USB Micro B connectors (only one can be used at a time.)
- Camera header for a OV7670 camera module (untested), doubles as GPIO header.
- Dedicated i2c header with 3.3V power pins
- Other breakout headers for power, onboard "headphone remote" ADC, microphone input, "BTRXD" UART pin.
- PCB contains area to build a 3.3V -> 5V boost converter based on TI TPS61240, which can be jumpered to the USB A connector. This is so the USB A connector can be used when the ZipIt is running on battery.
NB: The 3.3V power supply in the ZipIt does not contain enough capacity to output 500mA @ 5V. (If you've measured the surplus current capacity of the 3.3V supply, please let me know and I'll post it here!)

Known Issues
-
Libraries are a bit of a mess, lots of piecemeal .mod files. Due for a cleanup.
-
Did I mention it hasn't been successfully made or used yet? Good. :)

Questions
How big is the Z2breakout PCB?
It measures 44.5 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Z2breakout use?
15 parts, built around the TPS61240DRV. 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 Z2breakout KiCad files?
From the projectgus/z2breakout repository on GitHub, at the commit this page was made from: the board is z2breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Z2breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask projectgus before reusing the design.
