　　评估板BTLC1000 Xplained Pro

　　The Atmel® BTLC1000 Xplained Pro extension evaluation kit is to evaluate the Atmel® ATBTLC1000-MR110CA BLE module. The BTLC1000 MR110CA module is based on Atmel’s industry – leading lowest power Bluetooth Low Energy 4.1 compliant SoC, ATBLTC1000-MU-T. The XPro extension can be plugged into any of the supported Atmel’s host MCU Xplained Pro evaluation boards to quickly add Bluetooth Smart connectivity to the existing host MCU platform. Supported by the Atmel Studio integrated development platform, the kit provides easy access to the features of the Atmel’s ATBTLC1000-MR110CA BLE module and explains how to integrate the device in a custom design.
