Hardware
4.3.5 Arduino Compatible Headers (J1, J2, J3, J4, and J12 - unpopulated)
This kit has five Arduino compatible headers; J1, J2, J3, J4 and J12. You can develop applications
based on the Arduino shield’s hardware.
Figure 4-8. Arduino Header
The J1 header contains I/O pins for reset, internal reference voltage (IOREF), and power supply line.
The J2 header is an analog port. It contains I/O pins for SAR ADC, comparator, and opamp. The J3
header is primarily a digital port. It contains I/O pins for PWM, I2C, SPI, and analog reference. The
J4 header is also a digital port. It contains I/O pins for UART and PWM. 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 A.6 Bill of Materials (BOM) on page 108 for the header part number.
