Line sequence defines red 5V, black GND, white RXD, green TXD
 
(Good news: it is suggested by the customer that the new design of this product has more 3.3V welding port, but we need to disassemble the USB shell for welding.)
 
Special note:
(a) this connection is only selling a brush line, a tool. We are not familiar with the method of use, so we cannot provide guidance on how to operate. Because there are so many models on the market, and everyone's hands-on ability is so different, we can't guarantee your success. More do not because of their own success and give us in the review or bad review, then we than dou e also complain!
(2) We sent each one is tested, here to remind buyers please do not get directly after the operation, so as not to think there is a problem. Start with a simple test. It's as simple as this: If you plug the cable into your computer, it says "find new hardware...." , with the multimeter black pen (GND), red pen respectively to connect (RX) and (TX) can measure the voltage, it indicates that the small board must be good. Here in particular, if the (GND) received equipment with voltage pin, add power will be burned, so the user must accurately detect the equipment pin before wiring, so as not to cause unnecessary losses!
Some buyers accidentally burn the chip or can not operate or the machine itself does not support the upgrade, just say there is something wrong with our small board and so on, please take a detour, thank you. In this case, no return or refund will be granted, and neither medium nor bad reviews will be accepted.
 
Note: when setting 3.3V and 5.0V output (this is to power the single chip microcomputer, upgrade machine is not needed), please pull out the small board from the computer, when setting the jumper, do not operate with power, so as not to damage the equipment.
 
Stitching method and instructions:
 
Please be sure to find the pin definition before connecting, especially GND must not be connected to the voltage pin, and RX and TX end should not be connected to the VCC pin, (actually measured some VCC pin voltage up to 14V). Wrong connection will burn wiring chip, must pay attention to, do not take their own small board experiment, otherwise burn out we do not have any responsibility. Be sure to find a good pin definition in connection.
 
Connection method: brush machine again only need 3 wires, generally only to RX TX GND three signal wires, VCC need not be connected. Above is 4, 5 needle friends, do not need to connect VCC and BT needle. When using, please connect RXD with target board TX, TXD with target board RX, GND with GND, if not, switch RX and TX.
 
 
 
Connection mode:
RX to TX.
TX for RX.
Ground to ground (GND to GND)
USB to Serial port board function:
1 Simple serial port communication.
2 Upgrade the router or ADSL firmware.
3 GPS serial port communication.
4 Upgrade disk firmware.
5 Easy to use, RX connected to MCU TX; TX is connected to MCU RX. No need to convert with MAX232.
6 Use in terminal; Common serial port debugging tools.
All kinds of satellite upgrade.
Such as... Universal USB to serial port small board
