ขาย JDY-33 Dual Mode Bluetooth SPP Bluetooth SPP-C Compatible with HC-05 / 06 Slave Bluetooth 3.0 ราคาที่ดีที่สุด

Product Introduction and Application    JDY-33 Bluetooth is based on Bluetooth 3.0 SPP BLE design, so it can support Windows, Linux, android, IOS data transparent transmission, working frequency band 2.4GHZ, modulation mode GFSK, maximum transmission power 6db, maximum transmission distance 30 meters, support users through AT Command to modify the device name, baud rate and other instructions, convenient and fast to use and flexible. The advantages of JDY-33 are very obvious. It supports SPP and Bluetooth communication with the computer, supports mobile APP or WeChat applet, and can also support communication with the master and slave of the JDY-18 host. Applications JDY-33 is classic Bluetooth BLE dual-mode Bluetooth, which can communicate with Bluetooth-enabled computers (desktops, notebooks), mobile phones (android), and IOS. Can be applied  ◆ Bluetooth POS machine  ◆ Thermal printer  ◆ Smart Home Control  ◆ Automobile ODB testing equipment  ◆ Application of various Bluetooth transparent transmission products  ◆ Shared charging treasure, shared weight scale Module parameters: Model: JDY-33 Working frequency band: 2.4GHZ Communication interface: UART Working voltage: 1.8-3.6V (recommended 3.3V) Working temperature: -40 ℃-80 ℃ Antenna: Built-in PCB antenna Transmission distance: 30 meters Master-slave support: slave Module size: 26.7 * 13 * 1.7 mm (length, width and height) Bluetooth version: Bluetooth 3.0 SPP BLE4.2 SMT welding temperature: <260 ℃ Working current: 6.5mA Deep sleep current: <10uA Transmit power: 6db (maximum) Receiving sensitivity: -96dbm SPP maximum throughput: 16K bytes / s (android, windows) When connected with Android and computer Bluetooth, the communication speed can reach 16k byte per second, and no packet loss (support serial port to send and receive data continuously) BLE: 4K bytes / s (android, IOS) When BLE is connected with IOS or Android, the communication speed is 4K per second (supports continuous transmission and reception of data at 38400 baud rate, it cannot be continuously sent above 38400 baud rate, and it takes time to add delay in the middle) Note: Due to manual measurement, please allow 1-3mm different.
