6.1.3 LaunchPad Development Kit: MSP-EXP432P401R

The MSP432P401R LaunchPad development kit enables you to develop high-performance applications that benefit from low-power operation. It features the MSP432P401R – which includes a 48-MHz ARM Cortex M4F, 95-µA/MHz active power, and 850-nA RTC operation, a 14-bit 1-MSPS differential SAR ADC, and an AES256 accelerator.

This LaunchPad development kit includes an on-board emulator with EnergyTrace+ Technology, which means you can program and debug your projects without the need for additional tools, while also measuring total system energy consumption (see Figure 14).
