Table 2-2 lists the MCP2221 UART and I
2
C pins that are connected to the PIC32MZ
DA device.

2.1.13 40-pin Expansion Connector
On the back of the starter kit is a 40-pin (2 x 20) header (J15) which can be used to add
expansion boards to the starter kit. The header provides 2-pin UART (through UART4
or UART6), I
2
C (through I2C2), SPI (through SPI1) and GPIO capabilities. Table 2-3
provides the pins and the functions available through them.

Note 1: 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.
