The Raspberry Pi Zero W is new and improved with a whopping upgrade! Can you guess what it is? (Hint: W). No, it’s not just a letter, it’s WiFi! That’s right, one of our favorite type of upgrades has reached the Raspberry Pi Zero board. Built-in WiFi is made possible with the BCM43143 WiFi chip addition. Sound familiar? A similar chip was also added to the Raspberry Pi 3 Model B. And like the Pi 3, the Pi Zero W also has Bluetooth Low Energy (BLE) on board.
