Bluetooth Low Energy (BLE) TinyShield allows you to connect your TinyDuino system to any compatible iOS or Android (4.3+) device using Bluetooth Low Energy (also known as Bluetooth Smart and Bluetooth 4.0). This technology is great for low power sensors and accessories and works with most modern phones without the need for jailbreaking on iOS devices. This TinyShield is based around the popular Nordic nRF8001chipset and allows wireless communication up to 10 meters away. The TinyShield also Includes power supply and level shifters on the board, so you can run your TinyDuino from 3.0V – 5V.

Note: This product is for ADVANCED USERS, and requires that the user develops their own iOS or Android BLE app in order to use this.
