Bộ Chuyển Đổi TTL Sang UART Và Bộ Chuyển Đổi Cho Arduino/HC-06 RF Bộ Thu Phát Bluetooth Không Dây Mô-đun Nô Lệ RS232

Product Features: 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 is connected through the pin status, and the KEY pin is invalid for the slave 2. LED indicates Bluetooth connection status, flashing means no Bluetooth connection, steady light means Bluetooth is connected and the port is opened 3. Baseboard 3.3V LDO, input voltage 3.6~6V, current is about 30mA when not paired, 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 is 10 meters in an open area, 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 the communication format of 8 data bits, 1 stop bit, and no parity. This is also a commonly used communication format and does not support other formats. 7. When the Bluetooth connection is not established, the baud rate, name, and pairing password can be set 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 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 be paired with various Bluetooth-enabled computers, Bluetooth masters, most Bluetooth-enabled mobile phones, PDAs, PSPs and other smart terminals. The slaves cannot be paired. Little common sense (very important): TXD: Transmitting terminal, generally expressed as its own transmitting terminal. Normal communication must be connected to the RXD of another device. RXD: Receiving end, generally expressed as its own receiving end, normal communication must be connected to the TXD of another device. Connect the TXD of the device to the RXD of the device during normal communication! Self-receiving and self-transmitting: RXD is connected to the TXD of other devices during normal communication, so if you want to receive the data sent by yourself, as the name suggests, that is, you receive the data sent by yourself, that is, your own TXD is directly connected to RXD to test its own transmission and reception Whether it is normal is a quick and simple test method. When a problem occurs, do this test to determine whether the product is faulty. Also called loopback test.
