Product name: Download cable USB to TTL
Length: 1 meter
Chip: PL2303HX, PL2303TA
Line sequence defined red + 5V, Black GND, green TXD, RXD white
?one?The connection just to sell a small plate, a tool. We are not familiar with the use of the method, it is not possible to vide guidance operations. Because the market model range, and each person's ability and far, so we do not you will succeed. Not to because he did not succeed and give us neutral or negative feedback, we also complain of than Dou E!
?two?We sent out each one is tested, here to remind buyers do not get direct manipulation after, so would not think there is a blem. First, do a simple test method is very simple: If you put the cable into a computer, the computer mpts to find hardware .... with a multimeter black pen then (GND), respectively, to pick up the red pen (RX) and (TX ) can be measured voltage, then the small plates must be good. note here, if there is (GND) voltage connected to the device pins, power must be burned, so the user before the connection must be measured accurately pin device, so as to avoid unnecessary losses!
Some buyers do not accidentally burned chip or not operating or the machine itself does not support upgrading, say we have a blem of a small plate, etc., so buyers please Bypass, thank you. Such circumstances do not give return or refund behavior, or receive in the assessment and evaluation.
Pin connection and description:
Before connecting pin assignments sure to find, ely GND must not be connected to the voltage pin, and RX and TX are not connected to the terminal VCC pin, the (actual measurement had some VCC pin voltage up to 14V.?Take the wrong turn will burn chip wiring, must be careful not to take their own small board to do the experiment, otherwise we are not responsible for any burn. We must find a good pin definitions in the access.
Connection method: Again Brush only need three lines, generally used only RX TX GND three signal lines, VCC no connection. The above is 4,5 needles friends, not to VCC and BT needle. Please use the RXD and target board TX phase, TXD and target board RX phase, GND connection GND, if not, were reversed RX and TX.
All modules have been tested double the !
Home must see:
Friends have bought this board electronic basis. At least to recognize RX TX GND VCC these things, do not know is that please do not buy, you buy it will not get.
Reiterating no electronic-based do not buy! ! OUR sold every piece modules have been tested in good condition before the issue of the owner himself, Paul intact hand, buyers do not blindly received the goods after receiving up circuit, to understand clearly before wiring operation, module ducts, once sold rebate does not change, please buyers aware! ! !
Note that we do notupgrade tutorial. USB to TTL only teach you how to upgrade panels and wiring.
Some buyers do not care or do not burn the module operation or the machine itself does not support upgrading, say we have a blem, and so the module, so buyers please Bypass, thank you. This module does not give returns or refunds behavior.
RX for TX;
TX to RX;
Surface -?GND to GND?
USB to serial platelet function:
1 simple serial communication.
2 or ADSL router firmware upgrade.
3 GPS serial communication.
4 hard drive firmware upgrade.
5 easy to use, RX received the MCU TX; TX RX received at the MCU connected to ground. Without the need for conversion MAX232.
6 Super Terminal in use; common serial debugging tools.
7 upgrade with a variety of satellite machine.
............... And other general-purpose USB-to-serial small board
