iChip™ CO2144 IP Communication Controller™ chip and Broadcom BCM43362 WiFi chipset. It is
packaged 45.21X24.88 RoHS-compliant module with two 1X15 PIN headers and onboard antenna.
Nano Socket iWiFi G2 N2 offers and supports large variety of features which among them:
Ten simultaneous TCP/UDP sockets
Two listening sockets
Webserver with two websites
SMTP and POP3 clients
DHCP client/server
POP3 SMTP client with MIME attachment
FTP client
TELNET client
SerialNET™ mode for serial to IP bridging
Gateway between a local network on it’s LAN/WLAN interfaces and a WAN on any of
it’s other interfaces
Switch between it’s WLAN interface and the Ethernet interface when acting as a WLAN
access point

9. Evaluation Board
The II-EVB-363-G2-N2 evaluation board enables you to evaluate the Nano Socket iWiFi G2 N2
without changing anything in your current development environment. Using a simple Windows-
based application on a PC, you can issue AT+i commands.
AT+i commands are used to configure parameter values into iChip’s flash memory and activate
Internet tasks such as email send, sockets, FTP sessions, configuration, and more.
A full description of AT+i commands can be found in the AT+i Programmer’s Manual on Connect
One’s website.
To help you evaluate the Nano Socket iWiFi G2 N2, Connect One supplies the iChip Config Utility.
This is a Windows-based application that contains intuitive dialog boxes to fully configure iChip
CO2144. It doesn’t require any knowledge of AT+i commands. It also contains local firmware update
tools. The iChip Config Utility allows you to perform specific Internet communication tasks such as
sending and receiving emails, activating iChip’s websites, entering SerialNET mode, and more. The
latest iChip Config Utility version and user manual can be found on Connect One’s website under
the Support section.
On board connectors allow a choice of Host interfaces:
