Technical Specifications¶
The Synapse Wireless E20 gateway is an ARM Cortex-A9 based Linux computer running Ubuntu. It incorporates a 2.4 GHz Synapse RF module that connects the device to SNAP-powered mesh networks. The gateway has Wi-Fi and Ethernet network connectivity, and serial connectivity is available through a Micro-USB connection. This arrangement provides for a wide range of possibilities for monitoring sensor networks, controlling remote devices, and driving the Internet of Things

Note
When running an application that demands unusually intensive CPU/Memory resources at 70C, the temperature on the processor core might reach up to 90C resulting in performance degradation. For more information, see http://cache.freescale.com/files/32bit/doc/app_note/AN4579.pdf.
Note
This equipment is certified by Underwriters Laboratories for operation in a maximum ambient temperature of 65°C. The product safety standard to which this unit is evaluated and certified, IEC 60950-1, and UL 60950-1 for the US and Canada, specifies a maximum temperature limit of 70°C on metal surfaces that may be touched. During operation, there is a slight temperature rise on the surfaces of the E20. Therefore, when installed into an ambient environment at 70°C, the surface temperatures on the E20 may exceed the limit of 70°C.

Warning
RF Exposure. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Note
Antenna and transmitters may be co-located or operated in conjunction with this device only if the transmitters do not simultaneously transmit. Otherwise, additional regulatory requirements will apply.
