Overview
The chipKIT Network Shield is an input/output
expansion board designed for use with the
chipKIT Max32™. It provides the additional
circuitry and connectors to allow the advanced
communications features of the
PIC32MX795F512L on the Max32 to be
utilized.
The Network Shield provides a 10/100 Mbps
Ethernet PHY to allow connection to an
Ethernet network. It provides the connectors
and load switch to support use of the USB 2.0
OTG controller to implement USB device, USB
host or OTG operation. It also provides two
CAN transceivers and connectors to allow
connection to two independent CAN networks.
Connectors are provided to allow connection to
2
two of the I C busses supported by the Max32.
In addition to the communications features, the
Network Shield also adds a 256Kbit I
EEPROM for non-volatile data storage and a
32.768Khz oscillator to allow use of the Real
Time Clock/Calendar (RTCC) peripheral in the
PIC32 microcontroller.
The Network Shield is designed to the same
form factor as the Max32 board.
