Carbondale, Illinois, August 15, 2012 – EMAC, Inc. a leader in compact low power Panel PC design and manufacturing introduces the PPC-E4+, an ultra compact Panel PC with a 4.3” WQVGA (480 x 272) TFT color LCD and 4 wire resistive touch screen. The dimensions of the PPC-E4+ are 4.8” by 3.0”, about the same as that of popular touch cell phones.

The PPC-E4+ comes with either Windows CE 6.0 or EMAC’s Embedded Linux distribution installed and fully configured on the onboard flash.  Just apply power and watch the PPC-E4+ user interface appear on the vivid color LCD screen. The PPC-E4+ compact Panel PC utilizes a System on Module (SoM) for the processing core allowing the user to easily upgrade to a faster SoM if more processing power, memory capacity or storage is required. The PPC-E4+ uses an embedded ARM 9 based System on Module that features a 400MHz fanless low power processor with video and touch. The PPC-E4+ supports up to 256MB of SDRAM, up to 1GB of Flash, and up to 8MB 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 power consumption.

The PPC-E4+ has three RS-232 serial ports, and one RS232/422/485 port. Also provided are 1 SPI & 1 I2C port, 1 USB 2.0 (High Speed) Host port, 1 USB 2.0 (High Speed) OTG Port, Audio Beeper and a battery backed real time clock. Two MicroSD flash card sockets provide for additional flash storage. The PPC-E4+ can be connected to a network using the 10/100 Base-T Ethernet controller and its onboard RJ-45 connector.   Optional Power Over Ethernet (POE) and Audio with line in/out available.

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

The PPC-E4+ starts at $375.00 USD per unit. For more information on the PPC-E4+ go to our website: http://www.emacinc.com/panel_pc/ppc_e4+.htm
