Expansion Board for Arduino - CC2540 BLE Shield v1.0 Bluetooth V4.0

BLE Shield v1.0 is a low-power Bluetooth 4.0 transmission module. Module uses a TI CC2540 chip configuration 256Kb space, support AT commands. You can use this module used in remote control, game controller, wireless data collection, intelligent home, and other fields. At the same time as the Shield series one, it is very easy to use in-line to the development board.

Features
