OpenPhoenux:GTA04

=GTA04 Overview= The GTA04 is an open hardware platform. Its design is roughly based on the BeagleBoard-xM.

Features
This is the feature list of the GTA04A4 (if integrated into an existing Neo1973/GTA01 or Freerunner/GTA02 case):
 * 2.8 inch LCD with VGA (640x480) and touch screen (single touch with pressure detection)
 * Processor: DM3730 (OMAP3), 800/1000 MHz, ARMv7 (Cortex A8), NEON, integrated DSP (TMS320C64x)
 * OpenGL© ES 2.0 capable 2D/3D graphics accelerator
 * 512 MB RAM
 * 512 MB/1 GB NAND Flash
 * microSDHC (up to 32 GB)
 * Quad-Band GSM, EDGE, UMTS HSDPA 14.4 MBit/s, HSUPA 5.76 MBit/s (Specs)
 * GPS 20 channel, int/ext. Antenna
 * FM receiver and transmitter, both with RDS
 * 802.11b/g, Bluetooth 2.0
 * USB 2.0: full OTG (Client, Charger, Host)
 * Camera 1.3 Mpx (optional accessory)
 * Sensors: 3-axis Accelerometer, 3-axis Compass, 3-axis Gyroscope, Barometer/Thermometer Ambient Light
 * Audio / Video: Ear, Microphone, (Stereo) Handsfree, 2.5mm 4pin AV Jack (Composite-Video- Out, Audio in/out, Remote Control)
 * stereo speaker support (only for Neo1973/GTA01 case)
 * Battery: replaceable 3.7 V LiIon, 1200 mAh
 * Others: 2 Buttons, 4 LEDs
 * internal RS232 (full level, RX/TX/RTS/CTS/RI) - for debugging, unbricking and optional console
 * Torch/Flash controller
 * RFID tag chip with 64 kBit EEPROM
 * IrDA (FIR) transmitter and receiver
 * fits into existing Openmoko Neo1973 or Freerunner case (reversible)
 * documentation (see Manual incl. schematics) of all GPIO and signal connections to support driver development and extensions
 * 2x 60 pin expansion connector (optional)

=Revisions=

GTA04A1/Openmoko Beagle Hybrid (2010)
A BeagleBoard-xM connected to a display-board, which fitted the case.

GTA04A2 (2010)
The first revision which integrated everything (SoC, Modem, Sensors, Peripherals, ...) on a single PCB.

GTA04A3 (2011)
This revision was sent out to early adopters and software developers, to explore the new open hardware platform.
 * GTM501 replaced by GTM601W
 * BMA180 accelerometer added
 * RFID-EEPROM added
 * expansion connector added



GTA04A4 (2012)

 * second LIS302 accelerometer removed
 * Sensors are no longer optional but always installed
 * Si4721 no longer optional but always installed

GTA04A5

 * BMP085 replaced by BMP180
 * BMA180 replaced
 * HMC5883 replaced
 * ITG3200 replaced by BMG160
 * GPS is always W2SG0084 (Sirf IV) and delivers pulse-per-second
 * 6 wire I2C expansion connector for external keyboard option or other purposes
 * prepared for Case Kit connectivity of earpiece and vibramotor
 * headset plugin detection improved
 * production related changes (i.e. components substituted because of EOL; no visible change in features)

This revision is currently (2014) awaiting a large enough pre-order/production batch size, to be produced:
