1. What is MSP432 clicker?
MSP432 clicker is an amazingly compact
starter development kit which brings the
innovative mikroBUS™socket to your favorite
microcontroller. It features MSP432, a 32-
bit ARM® Cortex®-M4 microcontroller, two
indication LEDs, two general purpose buttons,
a reset button, a USB Micro connector and a
single mikroBUS™socket. A JTAG connector and
pads for interfacing with external electronics
are provided as well. The mikroBUS™connector
consists of two 1x8 female headers with SPI,
I2C, UART, RST, PWM, Analog and Interrupt
lines as well as 3.3V, 5V and GND power lines.
MSP432 clicker board can be powered over a
USB cable .

Figure 5-1: Two buttons, two LEDs and a reset button
5. Buttons and LEDs
The board also contains a 01 reset button and a pair of 02 buttons and 03 LEDs. Each of these additional peripherals are located
in the bottom area of the board. Reset button is used to manually reset the microcontroller. Pressing the reset button will generate
a low voltage level on microcontroller’s reset pin. LEDs can be used for visual indication of the logic state on two pins (P6.0 and P6.1).
An active LED indicates that a logic high (1) is present on the pin. Pressing any of these buttons can change the logic state of the
microcontroller pins (P1.0 and P1.1) from logic high (1) to logic low (0).
