โมดูลตัวรับส่งสัญญาณบลูทูธไร้สาย HC-05 HC 05 HC-06 HC 06 RF RS232 TTL เป็น UART สําหรับ ard
1. The core module uses the HC-06 slave module and the lead-out interfaces include VCC GND TXD RXD and reserved LED status output pins. The microcontroller can judge whether the Bluetooth has been connected through the pin status and the KEY pin is invalid for the slave.
2. The led indicates the Bluetooth connection status flashing indicates that there is no Bluetooth connection and the steady light indicates that the Bluetooth is connected and the port is opened
3. The bottom board is 3.3V LDO the input voltage is 3.6~6V the current is about 30mA when not paired and about 10mA after pairing the input voltage must not exceed 7V!
4. The interface level is 3.3V which can be directly connected to various single-chip microcomputers (51 AVR PIC ARM MSP430 etc.) and 5V single-chip microcomputers can also be directly connected without MAX232 or through MAX232!
5. The effective distance in open area is 10 meters more than 10 meters is also possible but the connection quality of this distance is not guaranteed
6. When used as a full-duplex serial port after pairing there is no need to understand any Bluetooth protocol but it only supports 8 data bits 1 stop bit and no parity communication format. This is also the most commonly used communication format. Other formats are not supported. .
7. When the Bluetooth connection is not established it supports setting the baud rate name and pairing password through AT commands and the set parameters are saved after power-off. Automatically switch to transparent transmission mode after Bluetooth connection
8. Small size (3.57cm*1.52cm) factory patch production to ensure patch quality. It is also covered with transparent heat shrinkable tube which is dustproof and beautiful and has a certain anti-static ability.
9. This link is a slave. The slave can pair with various Bluetooth-enabled computers Bluetooth masters most Bluetooth-enabled mobile phones PDAs PSPs and other smart terminals. The slaves cannot be paired.
