ITEAD BLE SHIELD

Overview

BLE shield is to adapt Bluetooth Low Energy to serial port, which is specifically designed for Arduino motherboard and compatible boards, plug and play. As the shield supports both 3.3V and 5V operating levels, it can be used together with other compatible motherboards such as ChipKit. BLE shield enables your Arduino board to communicate with other BLE devices, that is, communication with IOS devices, including iPhone 5, iPhone 4S, iPad 3 and iPod touch 5 can be achieved.

Features

• Supports both 3.3V and 5V operating levels, compatible with more motherboards
• Serial port connection selector, you can randomly choose connection between BLE shield and UART of the motherboard
• Onboard reset button
• With interface for electronic brick, you can easily connect a variety of electronic brick modules
