We only guarantee that the serial communication is normal, do not know how to brush, do not provide technical support for the brush, if you encounter other difficulties, please go to the professional Brush Forum for help. Thank you. Drive data downloadhttp://pan.baidu.com/s/1kTDhe0vLine order definition red +5V, black GND, white RXD, green TXD Special Note:(a) This connection only sells small plates, a tool. We are not familiar with the method of use, so we cannot provide guidance on the operation. Due to the large number of models on the market, and everyone's ability to operate is very different, so we do not guarantee that you can succeed. Not to give us a middle or bad review because we didn't succeed, then we have more complaints than Dou Huan!(b) Every one of us sent out is tested. Here, we remind the buyer to not operate directly after it is received, so as not to be considered to be a problem. First of all do a simple test, the method is very simple: If you insert the line on the computer, the computer prompts "find new hardware ....", with a multimeter black pen (GND), the red pen to connect (RX) and (TX) can measure the voltage, then the small board must be good. Here specifically stated that if (GND) is connected to the voltage pins of the device, the power must be burned, so the user must accurately measure the device pins before wiring to avoid unnecessary losses!Some buyers accidentally burned the chip or did not operate or the machine itself does not support the upgrade, saying that there is a problem with our small board, etc. Please ask such a buyer to bypass, thank you. In this type of situation, no return or refund will be given, nor will there be a mid-point review or bad review.Note: When setting 3.3V and 5.0V output (this is the power supply to the microcontroller, the upgrade machine is useless) Please pull the small board from the computer, take the jumper and do not use the power to avoid damage to the equipment.Pin connection and instructions:Please be sure to find the definition of the pin before connecting, especially GND must not be connected to the voltage of the pin, and RX and TX end should not be connected to the VCC pin, (actually measured some VCC pin voltage up to 14V.) wrong We must switch to the wiring chip, be sure to pay attention, do not take your own small board to do the experiment, otherwise we will not be responsible for any damage. Be sure to find a good definition of the pin.Connection method: To say that brush only requires three lines, generally only use RX TX GND three signal lines, VCC do not take. The above is a 4 or 5 pin friend, do not take VCC and BT needles. When using, please connect RXD with target board TX, TXD connect with target board RX, GND connect to GND, if not, swap RX and TX.All modules are factory tested in double!Connection method:RX to TX;TX to RX;Ground to ground (GND to GND)USB to serial small board 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 MCU's TX; TX is connected to the MCU's RX. There is no need to convert with MAX232.   6 Use in HyperTerminal; commonly used serial debugging tools.   7 Various satellite machine upgrades.     Etc...............Universal USB to Serial Board  If you don't know much about your own machine, you can go to this forum to see where you can find something you want: http://bbs.lcdhome.net/thread-htm-fid-31.html (forum)GeneralBrandZHAOYAOQuantity1 setMaterialABS shellSpecificationEnglish Manual / SpecNoOther FeaturesCertification-Packing List1 x Conveter ModulePackage Weight:0.04kg (0.088lb)Package Size:10cm x 10cm x 5cm (3.94in x 3.94in x 1.97in)
