myPhone is a TuxPhone
The TuxPhone proved the basic concept of a completely open phone (COP) with open software and open hardware, with all specifications of all the components freely available.
- Software
- See the open mobile software page.
- OpenCell
- OpenCell is being built by a team at Florida Tech, and we are sharing ideas and encouragement.
myPhone can be built from the following components, in any combination, landscape or portrait oriented screen.
- Case
- a customizable case that can be produced on a 3D printer. A first attempt at a bezel and an initial myPhone case for a 4.3" LCD have been designed using Alibre Express and printed at Techshop. Next step is a portrait oriented case for a 3.7" LCD with more rounded styling.
- LCD Touch Screen
- Sharp 4.3" 480x272 pixels as used in the Sony PSP, with a Hantouch touchscreen overlay added. This LCD has deeper color resolution than most, a true 8bits/pixel rather than 6bits for many others, but has relatively low pixel resolution. It's a low cost option, that needs more complex interfacing circuitry.
- There is also a higher resolution 4.3" at 800x480 with integrated touchscreen that is being investigated.
- OpenCell and the portrait oriented myPhone are using a Sharp 3.7" 480x640 pixels which is portrait format with integrated touchscreen.
- CPU
- Gumstix PXA270 600MHz CPU and I/O cards, dimensioned DXF specs
- Freescale i.MX31 is another option that includes graphics/multimedia processing, more open documentation than the later models in the PXA series, and could be the basis of a more compact custom design.
- GSM Modem and optional GPS
- GSMstix - Siemens MC75 GSM/EDGE and ublox Global Positioning System Module or Telit GM862 Module or the Telit GM862-GPS. GPS Antenna specification.
- Codec
- NXP UCB1400 audio CODEC with integrated touch screen controller and power management monitor
- WiFi/Bluetooth
- Embeddedworks Infineon Embedded Bluetooth and 802.11b/g module with CF interface.
- Bluetooth keyboard for people who want more than a touchscreen for input.
- the Bluetooth Frogpad for one handed typing.
- Thinkoutside/iGo makes a Stowaway "universal" Bluetooth folding keyboard.
- Accelerometer
- Freescale MMA7260QT ?
- Camera
- It would be nice to have a front mounted camera option for people who want to build video-phones.
- Video-out
- A TV-compatible video out feature would also be useful for presentations and projectors.
- Battery
- many options, but one high capacity, low cost, easily available possibility is 51x39x9mm Treo 650/700 3184WW 1800mAh.
- A higher capacity option in the Treo form factor is 2400mAh

Open Microprocessor Module
An Open Microprocessor Module design based on the Freescale i.MX31 has been started, and may serve as the basis for a broad range of potential mobile devices including MyPhone.
