HM-10 BLE Bluetooth 4.0 Wireless Module

HM-10 BLE Bluetooth 4.0 Wireless Module

The HM-10 BLE Bluetooth 4.0 Wireless Module enables wireless communication through BLE technology for embedded systems to connect with other BLE-capable devices such as Android, iPhone, and iPad.

The Bluetooth 4.0 HM-10 is highly customizable through a comprehensive AT command-set, which is well-documented for easy use. This breakout board for cc2541 enables seamless data transmission via serial UART with a default baud rate of 9600bps. It also features LED pins, RX/TX, and a voltage regulator that converts 5v to 3.3v.

The HM-10 and HM-11 series Bluetooth modules utilize the TI CC2540 chip, providing a 256KB configuration space and full compatibility with AT commands. This allows for customizable parameters such as changing the role (master or slave), serial port baud rate, device name, and matching password. The ease of customization makes these modules incredibly versatile in their usage.

This Bluetooth module offers a comprehensive, user-friendly, and reliable solution for data transmission, remote control, and data acquisition. It combines master-slave capabilities with transparent transmission, eliminating the need for a serial port. With its remote control and data acquisition features, an MCU is not required.

This section provides an overview of the pin configuration for the HM-10 BLE Bluetooth 4.0 Wireless Module

• Test pins, typically attached to an internal LED, generally remain disconnected.
• BRK, or break connect, refers to disconnecting the Bluetooth connection. It is typically advised to leave it unconnected.
• The VCC serves as the positive pole of the power source.
• GND, also known as Ground.
• The TX refers to the serial interface and transmitting terminal.
• RXD is a serial interface used for the receiving terminal.

Characteristics of HM-10 BLE Bluetooth 4.0 Wireless Module:

• This product offers both user-friendly operation and full encapsulation.
• You have the option to set it as a slave or master.
• Utilize the AT command to configure the baud rate.
• Provides coverage of up to 60 meters.
• Incorporated PCB antenna.
• Designing a UART.
• Bridge direct-driven mode can be supported simultaneously without requiring an additional CPU.
