GHI offers In-Field update feature on Embedded Master (not available on USBizi). Using
this feature, the user can update the GHI firmware or the managed application over the
Internet, USB or any possible way to get the firmware files.
Although, extensive testing is done on this feature, the user must take caution that it may
fail in certain situations (for example a power loss). Therefore, the user should still expose
another way to update the firmware, see Updating Embedded Master Firmware section.

11.21. Wireless LAN WiFi (IEEE 802.11b)
Embedded Master includes driver for ZeroG
ZG2100/ZG2101 modules which are SPI-bus based, low-
cost and FCC certified which make it ideal for Microsoft
.NET Micro Framework solutions.
The only difference between ZG2100 and ZG2101 is that
ZG2100 hosts an on-board antenna and ZG2101 includes
a connection for an external antenna.
To get started with WiFi support on ChipworkX, GHI
Electronics offers MFW-WiFi expansion that hosts ZeroG
ZG2100 module. and can be easily plugged in ChipworkX
or Embedded Master development system.
