Special note:

( a ) the connection just sell the boss, a tool. Our method for use is not familiar with, so to provide operational guidance. Because of the market of various types, and each person’s ability and differ very far, so we don’t guarantee your success. More than just because they did not succeed and give us comments or bad review, we more badfeelings!

( two ) we sent to every one is tested, here to remind buyers do not get directly after operation, so as not to be that is a question. First do a simple test, the method is very simple: if you put a line is inserted on the computer, computer tips «found new hardware…. «, with a multimeter black pen to answer (GND ), the red pen are respectively to meet ( RX ) and ( TX ) can measure voltage, then the boss must is good. Here special note, if (GND ) received equipment are voltage pins, power must be burned, so the user connection must accurately measure equipment, so as to avoid unnecessary loss!

Some buyers burned chip or not or operating the machine itself does not support the upgrade, that is our boss has a problem and so on, please buyers bypass, thank you.Such a situation will not return or refund the behavior, not receiving the neutral and negative comments.

Note: in the setting of the 3.3V and 5.0V output ( this is the SCM supply, upgrade machines don’t have ) please boss pulled out from a computer, in the setting of jumperrisk, do not live operation, so as not to damage the equipment.

Pin connection and instructions:

Before the connection please find pin definition, especially GND must not be connected to a voltage pins, and RX and TX end not connected to the VCC pin, ( actual measurements of some VCC pin voltage up to 14V. ) Take the wrong will burn through line chip, must notice, don’t take your boss to do the experiment, or burn without any responsibility on our part of. We must find a good pin definition in the ground.

Connection method: repeat brush machine only needs 3 line, generally only used to RX TX GND three signal lines, VCC don’t have to pick up the. It is 4, 5 needle friends,don’t have to pick up VCC and BT pin. Please use RXD target board is connected with TX, TXD and target RX. GND, GND, if not, swap RX with TX.
