Presenting Arduino Nano 33 BLE Sense and Raspberry Pi Pico
A microcontroller board is a printed circuit board (PCB) that combines the microcontroller with the necessary electronic circuit to make it ready to use. In some cases, the microcontroller board could integrate additional devices to target specific end applications.
Arduino Nano 33 BLE Sense (in short, Arduino Nano) and Raspberry Pico are the microcontroller boards used in this book.
Arduino Nano, designed by Arduino (https://www.arduino.cc), is a board that combines a microcontroller (nRF52840) powered by an Arm Cortex-M4 processor with several sensors and Bluetooth radio for an easy TinyML development experience. We will require just a few additional external components when developing on Arduino Nano since most are already available on-board.
Raspberry Pi Pico, designed by the Raspberry Pi Foundation (https://www.raspberrypi.org), does not provide sensors and the Bluetooth module on-board. Still, it has a microcontroller...
