SN111 - End Device
The SNAP End Device has the onboard peripherals to demonstrate powerfulmonitoring and control
capabilities right out of the box. You can control external electrical devices withthe power-relay, display
link-quality or other parameters on the 7-segment LEDs, wake up with a button-press, and more.
Several of Portal’s sample scripts make specific use of these boards. Modify one of the sample scripts
to make your own application – demonstrate for yourself the power of SNAP!
SNAP Node End Device™ (SN111)
The SN111 End Device provides a latching relay for controlling external
devices, and a sensor input with jumper-selectable pullup resistors which
allows the connection of a number of off-the-shelf resistive sensor types
such as photocells and thermistors.
Compatible with all Synapse RF Engines
RS-232 port with full hardware flow control(UART1)
2-Digit 7-segment LED, softwarecontrollable
Status LED and select switch, also under users oftwarecontrol
Battery or external power option
USB port (UART0) which can also provide power
10A latching relay
