## Description

The HM-11 is a Bluetooth Low Energy (BLE 4.0) module based on the TI CC2541 microprocessor. It provides wireless communication with smartphones, tablets, desktop computers, and other embedded systems via a simple UART serial interface with AT command control. The XBee-compatible form factor makes it easy to integrate into existing designs. Configurable as master or slave, with adjustable baud rate, device name, pairing password, and transmit power levels. Effective range is up to 30 metres in open environments. Key Features Bluetooth 4.0 BLE – Low-power wireless communication CC2541 Processor – TI's proven BLE SoC XBee Form Factor – Drop-in compatible with XBee sockets UART Interface – Simple serial (TTL) communication AT Command Set – Configure role, baud rate, name, password, and TX power Adjustable TX Power – −23 dBm to +6 dBm 30 m Range – In open environments Specifications Bluetooth Version: 4.0 BLE Processor: TI CC2541 Frequency: 2.4 GHz ISM band Modulation: GFSK Interface: UART (TTL) Supply Voltage: 3.3 V DC Current Draw: 50 mA Operating Temperature: −5 °C to +65 °C PCB Size: 24.5 × 30.5 × 0.8 mm Certifications: FCC, CE, RoHS Ideal For BLE communication with iOS and Android apps Wireless sensor and data logging projects IoT prototyping with XBee-compatible sockets Remote control and monitoring applications Package Contents 1× HM-11 Bluetooth Low Energy Module Resources HM-11 Datasheet (PDF) CC2541 Datasheet (TI) AT Command Reference Arduino Demo Code
