ESP32-C3-DevKitM-1 is an entry-level development board based on ESP32-C3-MINI-1, a module named for its small size. This board integrates complete Wi-Fi and Bluetooth LE functions. Most of the I/O pins on the ESP32-C3-MINI-1 module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C3-DevKitM-1 on a breadboard. Specifications ESP32-C3-MINI-1 ESP32-C3-MINI-1 is a general-purpose Wi-Fi and Bluetooth LE combo module that comes with a PCB antenna. At the core of this module is ESP32-C3FN4, a chip that has an embedded flash of 4 MB. Since flash is packaged in the ESP32-C3FN4 chip, rather than integrated into the module, ESP32-C3-MINI-1 has a smaller package size. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output. 5 V Power On LED Turns on when the USB power is connected to the board. Pin Headers All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board. For details, please see Header Block. Boot Button Download button.

The ESP32-PICO-Kit fits into a mini breadboard. It is fully functional with the minimum number of discrete components, while it has all the ESP32 pins exposed.
Features
Complete up-to-date documentation is available.
All instructions and commands presented work as described.
Plentiful additional information and hardware documentation are available too.
Applications for the ESP32-PICO-KIT can be developed on Windows, Linux or Mac.
Two cores and a radio
Like the ESP8266 the ESP32 has Wi-Fi but adds Bluetooth. It also has two 32-bit cores inside, making it extremely powerful, and providing all the ports and interfaces that the ESP8266 is lacking.Oversimplifying things, one might say that the ESP8266 is a Wi-Fi controller that provides some I/O, whereas the ESP32 is a full-fledged controller that also has Wi-Fi.
ESP32 peripherals
The ESP32 exposes an ADC & DAC, touch sensor circuitry, an SD/SDIO/MMC host controller, an SDIO/SPI slave controller, an EMAC, PWM to control LEDs and motors, UART, SPI, I²C, I²S, infrared remote controller, and, of course, GPIO.
ESP32-PICO-KIT Development board
The ESP32-PICO-D4 is a System-on-Chip (SoC) integrating an ESP32 chip together with a 4 MB SPI flash memory in a tiny 7 x 7 mm package.
The ESP32-PICO-KIT is a breakout board for this SoC with an onboard USB-to-serial converter for easy programming and debugging.
Besides the board, you'll need a programming toolchain. Complete, up-to-date documentation from Espressif is available on the Read the Docs website.
All instructions and commands presented work as described.Plentiful additional information and hardware documentation are available too.
Applications for the ESP32-PICO-KIT can be developed on Windows, Linux or Mac.

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.
