1、Brief Introduction 
 Tricoteco’s TT2540EM is the new generation Bluetooth 4.0 low energy wireless receiving and transmiting module, based on CC2540 low energy Bluetooth SOC chip, the clients don’t need to worry about the RF development, it all have been done .All digital interfaces have been led out, this extends module’s storage capacity. The module will have enough storage space to use,Whatever how the protocol will update in the future. TT2540EM’s software support the industry leading Bluetooth 4.0 low energy protocol bleStack software package, this is convenient for client to develop the product accord with Bluetooth 4.0 low power cost standard or other private standard.
 TT2540EM adopt CC2540F256 chip, mating with 5dBi antenna, the longest sight range of receiving and transmiting data can reach 200 meter,dimension 39mm*34mm.Mating with our development board,it is more convenient for testing and developing wireless communication product.
