CSR HM-11 Module

This is a SMD BLE module used in our BLE Bee and Xadow BLE. It is based on TI cc2541 chip, enables robust network nodes to be built with low total bill-of-material costs and highly suited for ultralow power consumption systems. The module is small and easy to use, with the preprogrammed firmware of manufacturer, you can quickly build BLE communications via its AT command. Supporting BLE communications with iphone, ipad and Android 4.3.FeaturesBluetooth protocol: Bluetooth Specification V4.0 BLEWorking frequency: 2.4 GHz ISM bandInterface way: a serial portOpen environment within 30 meters can realize communication between modulesTo send and receive no byte limit between modulesModulation method: GFSK (Gaussian Frequency Shift Keying)Transmission power: - DBM, 23-6 DBM, 0 DBM, 6 DBM, can be modified by the AT commandUse TI CC2541 chip, configuration space of 256 KB, support the AT command, the user can according to need to change the role (master, slave mode) and the serial port baud rate, name of equipment, matching parameters such as passwords, use agile.Technical detailsDimensions 60mm x90mm x2mmWeight G.W 1gBattery ExcludePower supply DC 3.3VCommunication protocol Uart(TTL)Default baud rate 115200bpsTransmit current 15mAReceive current 8.5mADeep sleep current 600uAOperating temperature -40 ~ +65¡ãCOutline dimension 13.5 x 18.5 x 2.3mmPart ListBluetooth V4.0 HM-11 BLE Module 1
