USB to serial CH340T ISP download module USB to TTL Product Description USB to serial new upgrade ! A change is not compatible with earlier versions of PL2303 WIN7 problem solving using CH340T chip system compatibility issues. Using high- quality materials , double-sided PCB board blue oil , good quality , convenient and practical pin interface leads . Note : C5 is itself does not require soldering , welding is not missing , do not worry ~ ~ USB to serial port, can replace the MAX232, leads to 51 single- copy program interfaces are +5 V, +3.3 V, GND, TXD, RXD. When used, the driver needs to be installed CH340T can only download the program , go after the driver took our websitesochange.cnTo download . Only three pins using a USB to serial , namely GND, TXD, RXD GND with microcontroller GND, TXD RXD connected microcontroller that P3 ^ 0, RXD TXD connected microcontroller that P3 ^ 1 Special note: We sent out each one is tested , here to remind buyers do not get directly after the operation , so as not think there is a problem . First, do a simple test method is very simple : If you take the line plugged into the computer , the computer prompts "Found new hardware .... " Black pen then with a multimeter (GND), respectively, to pick up the red pen (RX) and (TX) can measure the voltage , then the small plates must be good. Special note here : If there is (GND) connected to the device pin voltage , power must burn , so the user before the connection must be measured accurately pin devices , so as to avoid unnecessary losses ! When used, the need to install drivers can only download the program . Be sure to look for before connecting to the pin definitions , especially GND must not be connected to the voltage of the pin , and the RX and TX side and do not pick up on the VCC pin , ( Actual measurement over some VCC pin voltage up to 14V.) Take the wrong turn will burn the chip wiring , must be careful not to take their own small plate experiment , otherwise we are not responsible for the burn .
