E Overview The chipKIT Network Shield is an input/output expansion board designed for use with the chipKIT Max32 microcontroller board. It has circuitry and connectors that enable you to exploit the advanced communications features of the PIC32MX795F512L microcontroller on the Max32. The Network Shield has a 10/100 Mbps Ethernet PHY to enable connection to an Ethernet network. It provides the connectors and load switch to use the USB 2.0 On-The-Go (OTG) controller to implement a USB device, USB host, or OTG operation. It also has two CAN transceivers and connectors to allow connection to two independent CAN 2 networks. Connectors are provided to enable connection to two of the I C busses supported by the Max32. Features include: An SMSC LAN8720 10/100 Ethernet PHY An RJ45 connector with integral magnetics A USB device and host connectors Two MCP2551 CAN transceivers Two 12-pin header connectors for CAN 2 Two I C daisy chain connectors 2 A 256Kbit I C EEPROM A 32.768 kHz oscillator The chipKIT Network Shield board. 2 In addition to the communications features, the Network Shield also has a 256Kbit I C EEPROM for non-volatile data storage and a 32.768 kHz oscillator for using the real-time clock/calendar (RTCC) peripheral in the PIC32 microcontroller. The Network Shield has the same form factor as the Max32 board. Copyright Digilent, Inc. All rights reserved.

USB Connectors The connector on top of the board is a standard USB A-type receptacle. This is used when the Max32/Network Shield combination is used as a USB host. Immediately below this connector is a USB Micro-AB connector. This connector is used when the Max32/Network Shield is used as a USB device or when using it as a USB OTG device. 2. Ethernet Connector with Integral Magnetics This connector is used to connect the Max32/Network Shield to an Ethernet network. 3. JP4: USB Host Connector Selection When the Max32/Network Shield is used as a USB host, this jumper is used to select which USB connector is being used. 4. J17: Power Pass-Through Connector This connector passes the power connector from the Max32 through the Network Shield and powers the Network Shield from the Max32. 5. J9 & J12: Analog Signal Pass-Through Connectors These connectors pass the analog input pins on the Max32 through the Network Shield. 6. CAN2 Connector This connector provides access to the signals for CAN2. 7. CAN1 Connector This connector provides access to the signals for CAN1. Copyright Digilent, Inc. All rights reserved.
