The above are the friends of 4 and 5 pins, do not need to connect the VCC and BT pins. Please use Connect RXD to the target board TX, TXD to the target board RX, GND Connect to GND, if not, switch RX and TXo RX to TX; TX to RX; Ground to Ground (GND to GND) USB to serial port function: 1. Simple serial communication. 2. Router or ADSL firmware upgrade. 3. GPS serial communication. 4. Hard disk firmware upgrade. 5. Easy to use, RX is connected to the TX of the MCU; TX is connected to the RX of the MCU. on the ground. without the need to convert with MAX232. 6. Used in the terminal; commonly used serial debugging tools. 7. Various satellite machine upgrades. .etc...Universal USB-to-serial board Instructions: 1. Install the driver, 2. Restart the computer, 3. Insert the module into the USB port of the computer, the system will automatically install the driver verb: move 4. Connect TXD and RXD (that is, use a Dupont line at one end Plug in the TXD-head and plug in the RXD), so that the module can send and receive automatically, 5.
