Product Description


Bluetooth Serial Port Module for Arduino HC-05

HC-05 master-slave 6pin JY-MCU anti-reverse, integrated Bluetooth

Looking for an easy way to wirelessly communicate with your Arduino microcontroller? This Bluetooth module is an inexpensive way to let your Arduino exchange data with an Android Phone, iPhone, or PC with a Bluetooth radio. This module works much like a PC modem, it is controlled using "AT" style commands and is easy to get running. This is a very popular board and many tutorials can be found online for using this Bluetooth module with your Arduino. These bluetooth modules are incredibly ubiquitous and there is LOTS of information on the internet about using them with your projects. Keep in mind that Vetco can't help you program these or hook them up, that part of your project is up to you!

 

This unit is powered off of 3.6V to 6V DC but is 3.3V logic level. You would need to use a logic level shifter to use this on 5V logic. See out Logic Level Shifter Here but remember to verify that this is the chip you need, before ordering.

For usability and price, this board is hard to beat.

Library Information From Someone

Here is some information from the manufacturer. Its made in China, so it can be a bit of a difficult read.

Product characteristics:
1, the core module using the HC-05 from the module, the lead interface includes VCC, GND, TXD, RXD, KEY pin, Bluetooth connection status pins (STATE), the output is low, the output is high after the connection
2, LED indicates the Bluetooth connection status, the flash indicates that there is no Bluetooth connection, the slow flash to enter the AT mode, the double flash indicates that Bluetooth has been connected and opened the port
3, the base plate is provided with anti reverse connection diode, with LDO 3.3V, input voltage of 3.6~6V, the current is about 30mA, when the pairing is about 10mA, the input voltage is forbidden to exceed 7V!
4, interface level 3.3V, can be directly connected to a variety of single-chip (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly connected, no need to MAX232 also can not go through MAX232!
5, open and effective distance of 10 meters (power level of CLASS 2), more than 10 meters is also possible, but not to the quality of the connection to do this distance
6, after the pair when a full duplex serial port to use, no need to know any Bluetooth protocol, support 8 data bits, 1 stop bit and parity of the communication format can be set, which is the most commonly used communication format does not support other formats.
7, you can pull up to 34 feet into the AT command mode settings parameters and query information
8, small size (3.57cm*1.52cm), the factory patch production, to ensure the quality of the patch. A transparent heat shrinkable tube, dustproof appearance, and anti-static ability.
9, through the AT command to switch to the host or slave mode, can be connected to the specified device through the AT command
10, support from the 4800bps~1382400bps standard baud rate

Product use:
Paired only need as the serial baud rate is fixed as can be used, so as long as it is to the "fixed baud rate, 8 data bits, no parity" communication format of serial device can directly replace the original wired serial without the need to modify the program. Such as data acquisition, smart cars, serial printers, outdoor dot matrix screen control, etc..
Matching with the computer: suitable for computer and equipment through the Bluetooth serial communication, the use of the same method with the serial port
Pairing with mobile phones: suitable for mobile phones and devices through the Bluetooth serial communication, the use of the same method with the serial port
Bluetooth host matching with the use: suitable for two devices directly through the Bluetooth serial communication, such as single-chip and single-chip, between the cable with the microcontroller, the use of the method and the serial port

Flexible use:
Baud rate transform, because the sender and the receiver can choose their own baud rate, when a small amount of data can be used as a baud rate transform equipment.
