RF-CC2540A1 Ble4.0 Bluetooth

The module runs at 2.4GHz
ISM band, with GFSK (Gaussian Frequency Shift Keying) modulation scheme. It has 40 channels
(channel space at 2MHz), among which there are 3 fixed radio channels and 37 data channels of
adaptive automatic frequency hopping. Physical layers can be combined with classic Bluetooth RF
to form a dual mode device. And 2 MHz’s channel space can prevent interference from adjacent
channels better. Besides, it has a wide output power adjustment (-23 dBm ~ 4dBm) and a high gain
receiving sensitivity of -93 dBm.

The module is designed to quickly connect electronic products with smart mobile devices, and can be
widely used in various electronic devices, such as instruments, logistics tracking, healthcare, smart
home, sports metering, automotive electronics, toys, and etc. With Android 4.3 smart devices integrated 

with BLE technology, it will be a trend that BLE will be the standard configuration of smart phones. And the

market demand on smart phone peripherals will increase geometrically. With this module, users can 

integrate their existing solutions or products in the shortest development cycle, to occupy the market in

the fastest speed, and to empower their company’s growth with the strength of new technology.

RF-CC2540A1 module using TI CC2540 development of high-performance wireless chip .

Is a low cost , highly integrated UHF transceiver . Follow a low -power Bluetooth protocol,

suitable for single- mode Bluetooth low energy applications . CC2540 integrates a 1Mbps

GFSK RF transceiver , and use a rich peripheral 8051MCU kernel provides significantly

better than competing products transmission coverage.
