ITEM NAME:3. 3V to TTL UART Module Serial Converter Download USB drive wire brush CP2 R1B3 3. 3V to TTL UART Module Serial Converter Download USB drive wire brush CP2 R1B3 This compact USB-UART module, led interface with 5V and TXD, RXD and GND and CTS, RTS, which TXD, RXD can directly received series MCU, RXD received MCU TXD, RxD RXD MCU receipt, for can also received connection Bluetooth, GPS module, equipment series, CTS and RTS in special occasions as a greenhouse hand signal, general without, for the first products of debugging LED charge Shang player yihou often light. The module using the USB drive, USB directly to the PC maker, also be connected to the USB extension cable. 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 minicontroller. 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 4 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.
