We shall be describing here all available features of the Flow G1.5 Gizmo as well as differences from the original G1 device. There are many new features as well as allot of rework on the enclosure and the PCB design. Some features have been removed and others added for decreasing the end price as well as for practicality reasons.

External Differences

As you can see from the above images the 1.5 generation Flow has many external differences from it's predecessor G1. These Differences are described as follows:

1.  External dimensions are: 116mm x 68mm x 18mm

2.  2 Top buttons have been removed for practicality reasons due to unnecessary functionality

3.  Status indication LED's have been added to the Top left side of the enclosure to indicate GSM & charging features

4.  Headphone Jack has been moved to the Top side of the device for ease of use.

5.  Speaker position changed and Speaker holes for best sound have been added

6.  640x480px camera has been removed leaving only the 1.3mp camera on the back

7.  Flash has been removed due to unnecessary functionality

8.  Enclosure has been redesigned for better structure as well as easier access and Assembly/Dis-assembly

9.  Decals have been added to the enclosure for easier understanding of each slot as well as Gizmo For You logo added on the back side of the enclosure

10.  2 Colors used for the enclosure - Black Matte and Silver, no Clear coating required

Hardware Differences

Not only the external look of the device has changed, everything has been redesigned from scratch and repositioned inside the Gizmo. Some components removed and others added. Below is the full list of available hardware features of the device:

1.  LCD - 480 x 640 px with Resistive Touchscreen (Unchanged), LED Driver changed for less components and better availability. LCD support added for best alignment with the enclosure. 

2. ZigBit 900MHz RF Module has been added to expand the applications for the device.

3.  Sound - Mono Speaker out & Stereo Headphone out with Auto off when headset is plugged in

4.  Battery Capacity - 1500mA Li-Po Battery in an Ultra Slim profile of 3.2mm

5.  Battery Charging - 400mA Charge rate through Power Supply of the device (USB Charging removed due to high capacity required to be charged)

6.  Camera - 1.3mp, no expansion PCB's required since the FLEX connector plugs directly to the FLOW G1.5 PCB.

7.  Power Management reconstructed with less components & optimized design.

8.  Single PCB design - reducing the cost and practicality in assembly

9.  GSM & GPS antennas as well as GSM module & Sim Card moved to the bottom of the device for better reception and reduced noise.

10.  Sim Card slot changed to a PopOut Slot with thinner profile.

11.  24pin connector reduced in IO count leaving only the necessary signals for development (Power, USB & Development cables from G1 unit are fully compatible with only difference in IO names of the Development cable)

12.  Internal Stability of the PCB increased with Mounting holes and holding brackets.

13.  6 Layer PCB design with optimized track placement & better shielding for noise reduction and sound improvement.

14.  General purpose buttons changed for softer and more accurate pressure assignment.

15.  BGA components removed for easier soldering, debugging and lower price.

16.  HDMI Out has been added through the 24pin Connector.

These are the differences of the G1.5 unit from G1. All features and designs have been made as described above for a more affordable end price as well as practicality issues and more reliable operation. We hope that these changes are only for the best of the FLOW project and that everyone benefits from the changes and improvements we made.

So let's recap. We have said what is changed and what isn't but not everyone is familiar with the previous versions and it is best to summarize all the features. So here they are, features and specifications for the FLOW G1.5:

1.   480 x 640 pixels 3.7" LCD with a resistive Touch- Screen

2.   HDMI Out through the 24pin connector

3.   1.3mp Camera

4.   ZigBit 900MHz RF Transceiver with internal antenna

5.   UC864-G Module (GSM-GPS-GPRS-UMTS with all antennas included)

6.   Mono Speaker for Audio

7.   Stereo Headphone Jack 3.5mm

8.   Triple Axis Accelerometer

9.   Battery Monitoring & Status (Temperature, Capacity and other info)

10.   1500mA Li-Po Battery in an Ultra Slim Profile of 3.2mm

11.   400mA Fast Charger (only though power supply)

12.   Vibrator Motor

13.   Device can be selected with the UC864-G module or without

14.   Device can be used with the Overo Fire or Overo Earth (it can be used with any one of       the Overo platforms but we only supply the Fire and Earth options in the shop)

14.1 Overo Earth Specifications are:

14.2 Overo Fire Specifications are:

15.   2 x General Purpose buttons (By default assigned to Home & Back in Android)

16.   Android Eclair Operating environment (at the time of his writing)

17.   External dimensions are: 116mm x 68mm x 18mm

18.   Simple and rigid enclosure with internal PCB support as well as support for all internal components. Enclosure is Colorized as seen on the picture above. (Custom colorization for larger quantities is available)

19.   6 Layer 1.2mm thick PCB Design with carefully routed tracks and shielded with Power planes.

20. Customizable internal switches for envelopment and debugging.
