The TPC-43B is a cost-effective computer with a color TFT LCD and touch panel plus power-over-Ethernet (PoE). Targeted at building automation and factory HMI applications, this standard, off-the-shelf, ARM-powered, wall-mount design features a WqVGA (480 × 272) 4.3?, color TFT LCD panel in landscape format, with 65,000 colors, an adjustable LED backlight, and a touch panel. The computer is powered by a standard Medallion CPU Module (an SA2410-650 is included). The ARM9 processor features 32 KB of cache, 64 MB of SDRAM, and 128 MB of NAND flash, plus a separate NOR flash for reliable bootloader and software update options. Power via PoE dramatically reduces installation costs and replaces power cables with a single CAT-5 cable for both power and Ethernet. The unit can also be powered from 10 to 30 VDC or 7 to 24 VAC. The unit offers low-power consumption and passive cooling that enables fanless operation. To reduce power consumption, software can turn the backlight on or off and control the brightness. A low-power, RTC with battery backup is included. Communication is via a full-speed, USB host port (USB type A connector), and it supports wireless expansion, such as 802.11 or Bluetooth. Also included is a 10/100-BaseT Ethernet interface with an RJ-45 connector featuring integrated LED status indicators. An RS-232 serial interface with an optional DE9 adapter to accelerate software development is also available. The unit ships with the proven Medallion Linux 2.6 plus drivers preinstalled. Pricing for units with all options except wireless is $399 in 10-piece quantities. Single units of the TPC-43B are available as development kits with full software development tools and support.
