Note
: When the PSoC 4200M is powered separately and not through the USB, remove the resistors R63 and R64 to avoid
leakage while measuring current.

Arduino Compatible Headers (J1, J2, J3, J4, and J12
—unpopulated)
This kit has five Arduino compatible headers
—J1, J2, J3, J4, and J12. Header J1 is marked
10
and header J2, J3, and J4
are marked
13
in
Figure A-15
. You can develop applications based on the Arduino Shield
’s hardware.
The J1 header contains I/O pins for reset, I/O reference voltage (IOREF), and power supply line. The J2 header is an
analog port that contains I/O pins for SAR ADC, comparator, and opamp. The header J3 also has I/O pins that support
connection to PSoC 4200M CAN. The J3 header is primarily a digital port that contains I/O pins for PWM, I2C, SPI, and
analog reference. The J4 header is also a digital port that contains I/O pins for UART and PWM. The J12 header is an
Arduino ICSP
compatible header for the SPI interface and is not populated. Refer to the “No Load Components” section of
the
Bill of Materials
for the header part number.
Note:
Pin P1[7] has a 1.0-uF capacitor connected to it. This is provided as a bypass capacitor for the PSoC 4200M SAR
ADC. Remember to remove this capacitor if you are planning to use this pin for any other purposes.
Additional Functionality of Header J2
The J2 header is a 9×2 header that supports Arduino Shields. Some pins from port 0, port 2, port 3, port 4, and port 6 pins
of PSoC 4200M are brought to this header. The port 3 and port 4 pins also connect to the onboard CapSense Gesture Pad
through 560-ohm resistors. When the CapSense feature is not used, you may remove these resistors if necessary to help
ensure better performance with these pins
.
Functionality of Unpopulated Header J12
The J12 header is a 2×3 header that supports Arduino Shields. This header is used on a small subset of Shields and is
unpopulated on the PSoC 4 M-Series Pioneer Kit.
Pmod Connector
– Digilent Pmod Compatible (J16—unpopulated)
This port supports Digilent Pmod Peripheral Modules (marked
8
in
Figure A-15
). Pmods are small I/O interfaces that
connect with embedded control boards through either 6 or 12-pin connectors. The PSoC 4 M-Series Pioneer Kit supports
the 6-pin Pmod type 2 (SPI) interface. For Digilent Pmod Peripheral Modules, go to
www.digilentinc.com
.
This header is not populated on the PSoC 4 M-Series Pioneer board. You must populate this header before connecting
Pmod Peripheral Modules
. Refer to the “No Load Components” section of the
Bill of Materials
for the header part number.
