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
also includes 1 high current relay output capable of driving
up to 1A. The board consumes less than 20 mA when fully
operational and less than 100 uA when powered down. When
powered by an external battery or power supply, the LP3500
series can be awakened from power save mode by an internal
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.
Its six serial ports enable the LP3500 series to easily connect
multiple devices such as Digi’s XStream® 2.4 GHz RF modem,
which can send and receive data up to 20 miles. Dynamic C®,
an easy-to-use C environment, includes a host of sample
programs and libraries that help to lower development costs
and reduce time to market from months to weeks.
BENEFITS
– Low power consumption less than 100 uA in power
save mode
– 8 A/D inputs with 12 bit resolution
– Digital outputs can sink up to 200 mA
– 6 serial ports for multiple device connectivity
– 16 protected digital inputs
– 1 relay output up to 1A
– Backup battery for data protection
– Data logger
