Raspberry Pi 3 is a microcomputer with an integrated Bluetooth and WiFi module. Very easy to use, it’s lightweight and has greater memory and computing capacity than the Arduino.
Microcontroller features
The Raspberry Pi 3B+ microcontroller uses the quad-core ARMv8 microprocessor. This processor operates at a clock frequency of 1200 MHz. It has NC kB RAM, NC kB EEPROM and 2 to 16 GB kB Flash memory (for programming and data logging).

The microcontroller has a WiFi chip, enabling it to connect to the local network, create a server or create its own network for other devices to connect to. The microcontroller has a Bluetooth chip that enables it to interact with other devices. The Raspberry Pi 3B+ microcontroller also has an SD card slot for storing files for a website, for example.
Power supply
The Raspberry Pi 3B+ operates on a voltage range of 4.9-5.2V, thanks to its on-board voltage regulator, while the microprocessor operates on a voltage of 3.3V. In normal operation, the microcontroller consumes up to 45mA (if no power is supplied) and can accept a maximum current of 20mA on each of its IO pins.
