LOW-POWER SINGLE-BOARD COMPUTER DIGI RABBIT SBC LP3500 SERIES Low-power single-board computer ideal for remote telemetry applications requiring I/O control and data logging capabilities The LP3500 series features built-in analog and digital I/O which Its six serial ports enable the LP3500 series to easily connect also includes 1 high current relay output capable of driving multiple devices such as Digis XStream 2.4 GHz RF modem, up to 1A. The board consumes less than 20 mA when fully which can send and receive data up to 20 miles. Dynamic C, operational and less than 100 uA when powered down. When an easy-to-use C environment, includes a host of sample powered by an external battery or power supply, the LP3500 programs and libraries that help to lower development costs series can be awakened from power save mode by an internal and reduce time to market from months to weeks. timer, an RS-232 signal or via polling on an external input. The LP3500 can be switched from power save mode to full operation via software control. In addition to the low-power features, the board can also function as a data logger since the battery backup feature provides worry free data storage.
