The PPC-E4-3354, an ultra compact Panel PC with a 4.3 inch WQVGA (480 x 272) TFT color LCD and a resistive touch screen. The dimensions of the PPC-E4-3354 are 4.8” by 3.0”, about the same dimensions as that of popular touch cell phones. The PPC-E4-3354 is small enough to fit in a 2U rack enclosure.

Unlike other compact Panel PCs, the PPC-E4-3354 comes with EMAC's Embedded Linux distribution installed and fully configured on the onboard flash disk. This allows the software engineer to concentrate on writing applications and not have to worry about configuration and setup. Just apply power and watch the User Interface appear on the vivid color LCD, Linux X-Windows desktop. Interact with the PPC-E4-3354 using the responsive, integrated touch screen.

The PPC-E4-3354 compact Panel PC utilizes a System on Module (SoM) for the processing core. This allows the user to easily upgrade, if more memory capacity, storage capacity or processing power is required. The PPC-E4-3354 includes an embedded ARM A8 SoM; this ARM System on Module features a 1GHz Fanless Low Power Processor with Video and Touch. The SoM provided with the PPC-E4-3354 supports up to 512MB of Embedded SDRAM, Up to 16GB of embedded eMMC Flash, and 16MB of serial data flash. Typical power consumption is less than 5 Watts and the LED backlight can be shut off when not in use to further decrease its power consumption.

The PPC-E4-3354 offers three RS-232 serial ports, and one RS232/422/485 port. Also provided are two USB 2.0 host ports, an Audio Beeper and a battery backed real time clock. A Micro SD card socket is provided for additional Flash storage. The PPC-E4-3354 can be connected to a network using the 10/100 Base-T Ethernet controller and its onboard RJ-45 connector.

When developing CE 6.0 application for the PPC-E4-3354, Microsoft Visual Studio 2005/2008 can be utilized. For Embedded Linux application development, EMAC provides a Free Eclipse IDE. Both Visual Studio and Eclipse provide everything the user needs for developing PPC-E4-3354 applications. All the compiling, linking, downloading, and debugging inherent to software development can be done from one easy to use high level interface. EMAC provides an SDK for the PPC-E4-3354, which contains source examples and drivers.
