Dedicated Programming and Communication Base: Provides a three-in-one function of power supply, program download, and serial port debugging for wireless modules such as XBee and Bluetooth Bee. USB to Serial Port Transparent Transmission: Converts the USB interface to a standard UART serial port, enabling transparent data transmission between the computer and the wireless module. Plug and Play: No external power supply is required; power and communication are provided via the Micro-USB interface. Professional Adaptation: Pin definitions are perfectly matched with the XBee/Bee series, eliminating the need for jumper wires and preventing poor contact. One-Click Download: Integrated automatic download circuit (controlling DTR/RTS), allowing for one-click programming when used with software such as Arduino IDE. Power Supply Voltage: 5V (USB bus powered) Serial Port Chip: FT232RL Supported Modules: XBee series: S1/S2/S2C/S3B, etc. (pin compatible) Bluetooth Bee series: Master/slave integrated Bluetooth serial module Other compatible packages: 20-pin 2.0mm pitch wireless modules Interface: Host side: USB (Micro-USB) Module side: 20-pin spring loaded connector (compatible with castellated holes and pin header modules) Indicators: Power (PWR), Transmit (TX), Receive (RX) Main Uses: Wireless module firmware programming: For programming/updating firmware or configuring parameters of XBee and Bluetooth modules Wireless communication debugging: Used as a USB-to-serial tool to monitor the transmission and reception data of wireless modules in real time Prototype development and testing: Conveniently connect wireless modules to a computer for functional verification in the early stages of a project Device configuration: Configure modules using AT commands via a serial terminal (such as CoolTerm, Putty) Color: Blue Material: PCB Package Contents: 1*Adapter Only the above package content, other products are not included.
