Long Distance Beacon BLE 4.0 BLE module CC2540 lower energy module TI CC2540

CC2540 RF-BM-S02 New RFSTAR low energy 4dBm  50m 2.4GHz BLE 4.0 BLE RF Module

RF-BM-S02 is a BLE module based on TI CC2540F256, an 8051 core BLE System-on-Chip (SoC). This PCB module integrates a 32 MHz crystal, a 32.768 kHz crystal, an LC balun, an RF matching filter, and a meander line PCB antenna. It is pre-programmed with the BLE 4.0 stack and an application communication protocol over its full speed USB interface. It can be used to design a USB dongle to easily establish BLE connection from a device to smart phones. Very low-power sleep modes are available. Short transition times between operating modes further enable low power consumption.
