Customized GTA04 Motherboard - to build your individualized device

We know that not everyone can use the standard GTA04 in their applications. There is a need for individualized devices, e.g. having a larger display or a different battery. And not all applications need UMTS or GPS or even the highest speed OMAP3 that is available.

To fulfil this demand, we can also provide custom variants of the GTA04 board by leaving some components unpopulated. Two 60 pin Board to Board connectors (Hirose DF40-60DP-0.4V) allow to interface to your application specific adapter board.

The pictures to the left shows the OpenPhoenux 3704, an example of such a handheld device with a GTA04 Custom board inside. It uses an Ortustech display with touchscreen and adds a RFID/NFC reader. It also has a "big" 3900 mAh battery inside.
