Overview
The chipKIT™ WiFi Shield is an interface
board designed for use with Digilent’s chipKIT
line of microcontroller boards such as the
Uno32™, uC32™, or Max32™. The chipKIT
line is a family of microcontroller boards based
on the high performance Microchip PIC32
family of microcontrollers.
The chipKIT WiFi Shield provides chipKIT
microcontroller boards the ability to connect to
and communicate with IEEE 802.11
compatible wireless networks.
The WiFi Shield also provides a micro-SD card
connector for use with micro-SD flash memory
cards. The chipKIT MPIDE SD library can be
used to read/write files stored on the micro-SD
card.
The WiFi Shield is intended for use with the
Digilent network libraries, DNETcK and
DWIFIcK, available for free download from the
Digilent web site. These libraries make use of
and include a custom version of the Microchip
Applications Library licensed from Microchip.
Early versions of the WiFi Shield use the
Microchip MRF24WB0MA WiFi module. Later
versions use the improved MRF24WG0MA
WiFi module.
