Book: Get Started with the NXP FRDM-MCXN947 Development Board
Develop projects on connectivity, graphics, machine learning, motor control, and sensors
This book is about the use of the FRDM-MCXN947 Development Board, developed by NXP Semiconductors. It integrates the dual Arm Cortex-M33, operating at up to 150 MHz. Ideal for Industrial, IoT, and machine learning applications. It features Hi-Speed USB, CAN 2.0, I³C and 10/100 Ethernet. The board includes an on-board MCU-Link debugger, FlexI/O for LCD control, and dual-bank flash for read-while-write operations, supporting large external serial memory configurations.
One of the important features of the development board is that it features an integrated eIQ Neutron Neural Processing Unit (NPU), thus enabling users to develop AI-based projects. The development board also supports Arduino Uno form factor header pins, making it compatible with many Arduino shields, mikroBUS connector for MikroElektronika Click Boards, and Pmod connector.
One of the nice things of the FRDM-MCXN947 development board is that it includes several on-board debug probes, allowing programmers to debug their programs by communicating directly with the MCU. With the help of the debugger, programmers can single-step through a program, insert breakpoints, view and modify variables and so on.
Many working and tested projects have been developed in the book using the popular MCUXpresso IDE and the SDK with various sensors and actuators. Use of the popular CMSIS-DSP library is also explained with several commonly used matrix operations.
The projects provided in the book can be used without any modifications in many applications. Alternatively, readers can base their projects on those given in the book during the development of their own projects.

This ESP32 terminal is a microcontroller based on the ESP32 master. It adopts Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240 Mhz, supports 2.4 GHz Wi-Fi and Bluetooth 5 (LE), and can easily handle common edge terminal device application scenarios, such as industrial control, agricultural production environment detection and processing, intelligent logistics monitoring, smart home scenarios and more.
The ESP32 module also has a 3.5-inch parallel RGB interface capacitive touch screen with a resolution of 320x480 to ensure perfect image output at a frame rate 60 FPS. The 4 Crowtail interfaces on the back of this terminal can be used with Crowtail series sensors, plug and play, and create more interesting projects quickly and conveniently. In addition, it is also equipped with an SD card slot for extended storage (SPI leads) and a buzzer function.
The ESP32 touchscreen supports ESP-IDF and Arduino IDE development and is compatible with Python/MicroPython/Arduino. It also supports LVGL, which is the most popular free and open-source embedded graphics library to create beautiful UIs for any MCU, MPU, and display type. Now it has also obtained the official certification of LVGL. LVGL's board certificate shows that the boards can be easily used with LVGL and has decent performance for UI applications. The onboard charging circuit and lithium battery interface can use the type-C power supply interface to supply power and charge the battery at the same time, providing more outdoor scene expansion possibilities.
