HM-10 BLE Bluetooth 4.0 CC2541 Wireless Module – Original

The HM-10 BLE Bluetooth 4.0 CC2541 Wireless Module – Original is a readily available Bluetooth 4.0 module, which can configure as either Master or slave. This module is used for establishing wireless data communication. The module is designed by using the Texas Instruments CC2540 or CC2541 Bluetooth low energy(BLE) System on Chip (SoC). You can use it simply for a serial port replacement to establish connection between MCU, PC to your embedded project and etc.

It is fully configurable by a rich and well documented AT command-set and allows transparent data communication via serial UART (default baud rate 9600bps). The Bluetooth 4.0 HM-10 is basically a breakout board for cc2541, it broke out the LED pins, RX/TX and also adding the voltage regulator that regular 5v to 3.3 v.

Features :

• It’s easy to use and completely encapsulated.
• You can set it as a slave or master.
• You can use the AT command set the baud rate.
• Coverage up to 60 meters.
• Built-in PCB antenna.
• UART design.
• Support bridge direct-driven mode simultaneously (no need for extra CPU).
• 20ms connection interval (default), quick to connect; Support AT instruction, to modify the baud rate of the serial port, gain MAC address and modify module name.
• Support AT instruction, to adjust the Bluetooth connection interval and control the forwarding rate (dynamic power consumption adjustment).
• Support APP; IO expansion.
• 2 channel ADC input (14 bit).
• 4 channel PWM (120Hz) output.
• The RSSI successive acquisition, auto read, and notification to APP (used in anti-lost alarm).
• Power indicator/alert.
• Support anti-hijack password setup, modification, and restoration.
• Ultra-low power consumption standby mode.
