Hardware
2.1.8 168-pin Modular Expansion Connector
The PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family Starter
Kit has been designed with a 168-pin modular expansion interface, which allows
the board to provide basic generic functionality and easy extendability to new
technologies as they become available.

2.1.9 Ethernet PHY
The Microchip LAN8740A PHY Daughter Board is populated with a low-power, small-
footprint, 10/100 Fast Ethernet LAN8740A PHY, which features Energy Efficient
Ethernet (IEEE 802.3az) and Wake-on-LAN functionality. This daughter board is
designed for easy development of RMII Ethernet control applications when it is
connected into a compatible PIC32 starter kit.
To use a different Ethernet PHY other than what is offered, visit the microchipDIRECT
website (www.microchipdirect.com) for the list of alternate options.
2.1.10 USB-to-UART/I²C Communication
To facilitate application debug and development, a MCP2221 USB-to-UART/I²C device
(U8) is available. The MCP2221 creates a virtual COM port on the personal computer
when a mini-USB cable is connected between J11 and the host personal computer. To
download the driver for the MCP2221, please visit the MCP2221 product page
(www.microchip.com/MCP2221).
Libraries are also available on the MCP2221 web site that allow the host PC to
communicate with the PIC32MZ EF device through the I²C bus. Pull-up resistors are
provided (R64 and R65).
If the features of the MCP2221 are not desired, disconnect the MCP2221 from the
PIC32MZ EF device by removing resistors R66, R67, R68, and R69.
Table 2-2 lists the MCP2221 UART and I²C pins that are connected to the PIC32MZ
EF device.

The CTS and RTS functions are not required, but are available if desired. The
MCP2221 configuration utility can be used to turn those functions on and off.
Three LEDs (D8, D9, and D11) are available to provide a visual indication of activity on
the MCP2221. D8 is a red LED, which indicates receive activity (data from the PIC32).
D9 is a green LED, which indicates transmit activity (data to the PIC32). D11 is a yellow
LED, which indicates activity on the I²C bus.
Note: Since the MCP2221 receive (RX) line shares the same pin as SW3, SW3
cannot be used in an application where the MCP2221 is also used.
