Arduino Nano 33 IoT [ABX00027] - 32-bit ARM Cortex-M0+, WiFi & Bluetooth, 256KB Flash, 32KB SRAM, Secure Element, 14 Digital I/O Pins, 6 Analog Inputs, Compatible with Arduino IDE for IoT Projects

Compared to the same size Arduino Nano or the larger Uno look at what you get: 1. 8 times the program memory (ROM) 2. 16 times the data memory (RAM) 3. 3 times the clock speed with 4x the register and data path width (so even faster computations than 3x) 4. A NINA Bluetooth/WiFi radio, if you want it. 5. A price tag about 3/4 that of the Nano or Uno. So what's not to like? 1. 3.3V instead of 5V can cause compatibility problems with peripherals designed for 5V only. 2. Different processor architecture (ARM instead of AVR) means that some Arduino software won't run. 3. No EEPROM. But if you need one, you can always attach an external one via I2C or SPI. 3. Fear of the unknown? So, yes it isn't a plug-in compatible replacement, but it is certainly worth a look. FYI, another favorite of mine is the Arduino Nano Every, which is even less expensive and again better in almost every way than the regular Nano and is 5 volts. Between these two it eliminates almost all desire for any other Arduino board.

I had been wrestling with getting a no name ESP32 board to work right and thought I would spend the extra money to try this board out. Clearly the Arduino Cloud environment is designed to make these boards much easier to us as my project came together super quick and easy with this board. Saved a lot of time that made the extra money worth it - for me anyway.

Arduino has always struggled versus the raspberry pi's ability to easily connect wifi, making the RPI the go-to choice for integrating to network services. However, the relative weakness of RPIs GPIO vs the Arduino's great PWM/Analog/Digital IO makes it more difficult to do simple hardware integrations with. I *love* this solution and have been thrilled with it. The WifiNINA library makes connecting trivial, and making web requests to post updates is so simple. I now finally have the best of both worlds - great IO and low power with simple reliable networking. The addition of Arduino Cloud is a nice touch, but the monthly cost has kept me from doing anything more than exploring that option a little bit. Great product, highly recommended.

Works great. My only problem was soldering wires to the board but I'm inexperienced at soldering. Nonetheless I successfully made the connections. Having Bluetooth already on the board was great.

Haven't actually hooked the think up yet... but soon. BUT... realized with some research that there's no support in Arduino libraries (that I've found) for BLE 4.2 JustWorks encryption. So I'm saying 4 our of 5, not about the product, but about the absence of that library. About time, isn't it?

This is my first experience using Arduinos. I've used RPIs for years. I'm impressed with the boot time, and size/power consumption. perfect little devices for my embedded project!

I've used ESP32 based board in a few projects now and it works very well. Granted you can get an ESP32 cheaper but if you just need it to work as expected this is an easy way to go.

Applied in a medical device project...

es lo que promete un mano con conexión WiFi para proyectos Iot, me ha servido en lo que necesitaba. solo comentar (yo no lo sabía) que entrega 3.3 V por lo que tal vez debas afectar tus sketch

After connecting 2nd time to usb and the board gets hot and unable to detect usb

This is a great item and was really easy to use! It was really useful for my university studies. The size and compactness of this product meant I could easily take it too and from where ever I was studying whether it was in a lab setting, in a lecture hall, library or in my accommodation!

Ein sehr spannender Arduino, da WLAN und BLE hier auf einem sehr kleinen Raum zu finden sind, im üblichen Format des Arduino nano und mit modernem Cortex M0+ Mikrocontroller! Ich habe eine Tutorial-Serie mit diesem Mikroprozessorboard auf Youtube gestartet, da es einen einfachen Einstieg in die Welt des IoT bietet. Suchbegriff: "Arduino nano 33 IoT mit MQTT cloud verbinden [DEUTSCH]" . Einzig der Preis ist etwas zu hoch, wenn man vergleichbare Produkte mit einem ESP32 oder ESP8266 betrachtet. Aber der nano 33 IoT ist ein offizieller Arduino, damit unterstützt man Pioniere der Maker-Szene!

Il reste très bon produit
