APPLICATIONS Sport and fitness sensors: heart rate, runner speed and cadence, cycle speed and cadence Health sensors: blood pressure, thermometer and glucose meters Mobile accessories: watches, proximity tags, alert tags and camera controls Smart home: heating control and lighting control 2. INTRODUCTION The MRB111 is a 2.4GHz low power Bluetooth v4.1 module which integrates a CSR1012 series BT chip and a printed antenna. It can either use the printed antenna on the module directly or go through a RF pin-out to a customer’s board to establish an external antenna system. However, this hardware option needs to be chosen while ordering. Interfaces of setting controls , such as UART, and SPI, are available. The module is a highly integrated and compact-sized PCB module with the dimensions of 9 x 9 X 1.3 mm. 3. FEATURES RF performance RX sensitivity: -90dBm, typical TX output power: 8 dBm , typical TX current consumption: 35 mA @3.3V, typical Rx current consumption: 20 mA @3.3V, typical Deep sleep current: 5.5 uA @3.3V, typical Idle mode current: 1.4 mA @3.3V, typical Data rate: 1Mbps MRB111<Rev. 0.2> page 3/ 9 MRB111 Setting interface UART 2 wires SPI 4 wires 4.
