hardware.
The J17 header contains I/O pins for reset, I/O reference voltage (IOREF), and power supply line.
The J18 header is an analog port that contains I/O pins for SAR ADC, comparator, and opamp. The
header J19 has I/O pins that support connection to PSoC 4200L communication blocks. The J19
header is primarily a digital port that contains I/O pins for PWM, I2C, SPI, and analog reference. The
J20 header is also a digital port that contains I/O pins for UART and PWM. The J24 header is an
Arduino ICSP-compatible header for the SPI interface. See
“Arduino-Compatible Headers” on
for details on the headers pinout.
Additional Functionality of Headers J17, J18, J19, J20
The headers J17, J18, J19, and J20 are two row headers. When the shield board is used along with
the main board (either without snapping or through J26 and J27), the odd pins on the header (pins 1,
3, 5, and so on) act as Arduino baseboard headers. These pins can interface to any Arduino shield
board and can work simultaneously with the main board Arduino shield-compatible headers (J1, J2,
J3, J4), as shown in
. When the shield board is snapped, the even pins (2, 4, 6, and so
on) act as Arduino shield headers. After the board is snapped, these pins can be used to convert the
shield board into an Arduino shield. The shield board can then be interfaced with any Arduino base-
board such as CY8CKIT-044, CY8CKIT-042, and others. By default, the female Arduino baseboard
headers (odd pins on J17, J18, J19, and J20) are populated on the board. After the board is
snapped, these female connectors should be removed and alternate connectors provided in the
BOM (under No load components) should be populated to use them as Arduino shields. See
for details on using the shield board as an Arduino shield.

EZ-BLE PRoC Module (U8 - unpopulated)
The board includes a footprint for mounting an EZ-BLE PRoC Module (marked 33 in
). The EZ-BLE PRoC Module is a fully integrated, 10×10×1.8 mm, fully certified, program-
mable module designed for ease-of-use and reduced time-to-market. It contains Cypress’s PRoC
BLE chip, two crystals, chip antenna, shield, and passive components. Refer to
