This Quick Start guide outlines the basic features of the Synapse SN132 SNAPstick USB
module.

Introduction:
The Synapse SNAPstick is designed to be a compact and easy way to connect a PC to a SNAP
wireless network.
The module supports all existing forms of the Synapse RF engine and is fully compatible with
Synapse’s Portal management software.
Supported Synapse RF Engine types:
•
•
•
RF Engine with built-in F antenna (RFE)
RF Engine with built-in F antenna and transmit power amplifier (RFET)
RF Engine with external antenna and transmit power amplifier (RFET)

OnBoard Indicators:
A Tri-color LED is available as an output indicator. This component has the ability to emit a red,
green, or amber light. It can be controlled by SNAPpy scripts (running on the SNAPstick) that
manipulate GPIO pins 0 and 1.

A second green LED is used to indicate that power is being supplied to the module. It cannot be
controlled by the user.
The SNAPstick does not provide access to any other of the 17 General Purpose Input/Output
(GPIO) pins available on the RF engines. These are accessible with other forms of Synapse
evaluation hardware.
Synapse offers 3 other types of SNAP nodes:
•
•
•
SN163 Bridge Demonstration Board
SN111 End Device Demonstration Board
SN171 Proto Board
USB Interface:
The USB interface on the SNAPstick communicates with the connected RF Engine via internal
UART 1. This UART is connected to GPIO pins 7-10. The following table describes their use.

Powering Options:
The SNAPstick can be powered using any form of standard USB connection.
Note: It must be a powered-USB connection.
(Examples include: a PC/laptop port, a powered-USB hub, or a stand-alone USB AC adapter)
The module does
not
require Synapse’s Portal software or other software drivers to be installed in
order to draw power from the PC’s USB port.

Taking Things Further:
Synapse offers a wide variety of alternate demonstration boards. These provide more control
over the input and output functionality of the SNAP RF engine. For example, the SN171 Proto
Board provides full access to all 19 GPIO pins and is available standalone or as a part of
Synapse’s
EK2500 evaluation kit.
The SNAPstick is featured in the Synapse
EK2100 Evaluation Kit.
This kit is designed to guide
the user through a basic SNAP network setup and a series of application demonstrations. It
includes all the hardware and software needed to gain a basic understanding of SNAP mesh
networking and the capabilities of SNAP nodes. More information is available online in the form of
the
EK2100 Users Guide.

networking can be found at our dedicated online support forum at:
