Description: Arduino Nano 33 IoT
The Arduino models in the Nano series are designed toextend the capabilities of small tilesto make their use possible in any project. Arduino Nano 33 IoT fits perfectly into the category ofInternet of Things (Internet of things, objects) projects thanks to the built-in WiFi andBluetooth NINA W102communication chipbasedon ESP32 module. Additionally, Nano 33 IoT is equipped with ATECC608A cryptography. It also supportsArduino IoT Cloud andTLS (Transport Layer Security) standard, which is a development of SSL protocol ensuring confidentiality and integrity of data transmission.

Arduino Nano 33 IoT capabilities
The heart of Arduino is a microcontrollerSAMD21G18AClockedto 48 MHzsupported by 256 kB flash memory and 32 kB SRAM. The board is equipped withNINA W102wireless communication module based on ESP32 chip. This enables communication via WiFi or Bluetooth.Security of transmitted data is ensured by cryptographic system ATECC608Aand the fact that Arduino Nano 33 IoTsupports Arduino IoT Cloud and TLS(Transport Layer Security)standard, which is a development of SSL protocol ensuring confidentiality and integrity of data transmission. There is enough space on the board for a 3 axis accelerometer and gyroscope.

Attention! By default, Arduino Nano 33 IoT can work ONLY with 3.3V. Do not connect to signal pins of devices operating at 5 V. |
By default, Arduino Nano 33 IoTsupports only 3.3 V. There is a jumper in the place of 5 V pin in standard Nano board (between RST and A7 pins) which can be shorted to USB power supply.To supply the devices with 5 V, solder the jumper and power Nano via USB. If the jumper is soldered and no voltage is obtained from the V in pin. This is a protection to protect Arduino Nano 33 IoT. The board allows debugging of programs, which is done with 6 pads on the bottom of the board underneath the communication system.

(*) Unlike the standard Arduino Nano, the A4 and A5 pins have a default pull-up, the so-called pull-up and are used as I2C bus, so it is not recommended to use them as analogue inputs.
