The Raspberry Pi Zero microcomputer is very compact, with an integrated Bluetooth and WiFi module. Very easy to use, it is smaller but less powerful than the Raspberry Pi3.
Microcontroller features
The Raspberry Pi Zero microcontroller uses the ARM11 single-core microprocessor. This processor operates at a clock frequency of 1000 MHz. It has NC kB RAM, NC kB EEPROM and 512,000 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 Zero microcontroller also has an SD card slot for storing files for a website, for example.
Power supply
The Raspberry Pi Zero microcontroller 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.
