Arduino Compatible Headers (J1, J2, J3, J4, and J12)
This kit has five Arduino compatible headers: J1, J2, J3, J4, and J12. You can develop applications
based on the Arduino shield's hardware. An Arduino shield compatible Trackpad board is also sup-
plied with the kit.

Note:
The graphic LCD shield in
is shown for reference only and not part of the kit.
■
The J1 header contains I/O pins for reset and power supply line.
■
The J2 header is an analog port. Because of limited analog support in PSoC 4000 family, it con-
tains general-purpose digital I/O pins only.
■
The J3 header is primarily a digital port. It contains I/O pins for PWM, I
2
C and general-purpose
digital.
■
The J4 header is also a digital port.
■
The J12 header is an Arduino ICSP-compatible header for the SPI interface. This header is not
populated. Refer to the "No Load Components" section of Bill of Materialsfor the header part
number.
Note:
The PSoC 4000 family does not support SPI in hardware, but SPI master can be implemented
on any pin using firmware bit banging.
