MSP432 Introduction

Msp432 is a 32-bit arm cortex M4 development Texas instrument board with ultra-low power consumption and high performance. This is another successor to the low-power development board called MSP430. The development board supports RTOS and arm architecture, so we can use the board for high-performance applications. At the same time, the board is designed to consume low power consumption, making it very suitable for battery powered applications.

How does a MSP432 work?

The launchpad purchased comes with the following:

  1. Brochures with leads and other useful information
  2. USB programming cable
  3. Msp432 board.

The msp432 board has two parts, the upper part is used for programming and debugging board, while the lower part includes the arm cortex MCU of the emulator part with a couple of switches and LEDs. These switches and indicators can be used to practice the program and debug them.

Where to use MSP432

Msp432 is a 32-bit arm cortex M4 development Texas instrument board with ultra-low power consumption and high performance. This is another successor to the low-power development board called MSP430. The development board supports RTOS and arm architecture, so we can use the board for high-performance applications. At the same time, the board is designed to consume low power consumption, making it very suitable for battery powered applications. The evaluation board also has power tracking options, which will help us monitor and improve the power consumption of the evaluation board. It has on-board emulator and supports energy IDE, so it is easy to program and debug. Therefore, if you are looking for a powerful MCU with arm architecture and can run at ultra-low power consumption, msp432 may be the right choice for you.
