ITEM NAME:CP2102 T1 3.3v to ttl uart module serial converter download usb drive wire3c The product descriptions Color: as shown Note: this product just to make your computer on a series with a variety of such standard equipment that GPS, satellite receiver, HDD, modules Bluetooth, such as communications. the head of machine serial port DB9 PC, level  ±12V and negative logic, if you want to receive single-chip MCU need serial Serial converter as MAX232 circuit are compatible with level MCU signal. Go USB serial port is 3.3V level of the output signal, can go directly to the 5 v or 3.3 v microcontroller. Communication General TXD, RXD, GND only when necessary. Therefore, transfer USB serial port can be received on the serial port MCU directly without using the circuit MAX232, more practical use. Package Contents: 1 x Module 5 x DuPont line Note:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3 cm.The head of machine serial port DB9 PC, level  ±12V and negative logic, if you want to receive single-chip MCU need serial Serial converter as MAX232 circuit are compatible with level MCU signal.
