USB Support to COM Module Cable USB to RS232 TTL UART PL2303HX

Line sequence defined red +5 V, black GND, green RXD, white TXD Note: 3.3V and 5.0V output is set (this is the power supply to the microcontroller, upgrade machines do not need the small plate) unplugged from the computer, set the to take, do not live to avoid damage to the equipment. The wrong connection be sure to find the pin definitions, especially GND must not be connected to the voltage on the pin, and the RX and TX terminal is not connected to the VCC pin (actual measurement of some VCC pin voltage up to 14V.) shall be burnt adapter cable chip, certain note, do not take their own small plate to experiment, or burn We are not responsible. Must find the pin definitions in . Connection method: repeat Brush only need three lines, generally used in the RX TX GND three signal lines, the VCC without access. The above 4,5 needle friend, not connected to VCC and BT needle. Use RXD connected with the target board TX phase, TXD and target board RX, GND connected to GND if not, swap RX and TX. Name: USB to TTL download cable Colour: Black material: plastic Length: 1 meter Chip: PL2303HX, PL2303TA Line sequence definition red +5v, black GND, green TXD, white RXD. Link mode: RX to TX, TX to RX, ground-to-ground, USB to serial port function: simple serial port, router or ADSL ancient sword upgrade, GPS serial communication, hard disk ancient sword upgrade. Easy to use, RX is connected to the TX of the MCU, and TX is connected to the RX of the MCU, and it is connected to the ground, without the need for MAX232 conversion. Used in HyperTerminal, serial debugging tools are commonly used, and satellites are used for upgrading. Package Contents: 1pcs x download line Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
