WIN7 system USB V2.0 500mA CH340G RS232 To TTL Module

CH340 module instead of PL2303 CH340G RS232 to TTL module upgrade USB to serial port in Brush small plate

CH340 is a USB bus adapter chip, to achieve USB serial port or USB print port.
Special point:

• full speed USB device interface, compatible with USB V2.0.
• simulation standard serial port, used to upgrade the original serial port peripherals, or add additional serial port via USB.
• computer - side Windows operating system under the serial application is fully compatible, no modification.
• hardware full duplex serial port, built-in transceiver buffer, support communication baud rate of 50bps ~ 2Mbps.
• supports commonly used MODEM contact signal RTS, DTR, DCD, RI, DSR, CTS.
• provides RS232, RS485, RS422 and other interfaces through external level conversion device.
• CH340R chip supports IrDA specification SIR infrared communication, supports baud rate from 2400bps to 115200bps.
• supports 5V power supply voltage, 3.3v power supply voltage and even 3V power supply voltage.

Features of PL2303HX:

1. Adopt imported controller RS232 TTL,which can stabilize the flash with high speed 500mA self recovery fuse for protectionTwo data transmission indicator can monitor data transfer status in real time
2. Reserve 3.3V and 5V pin interface,easy for the DDWRT of different voltage system that need powerThe entire board is coated by high quality transparent heat-shrinkable sleeve,making the PCB in insulation state from outside,so that the board won't burnt down by material short cut.
3. Electrostatic package,insures the board will not be damaged before useSupport WIN7 system
4. Specifications:Dimention: about50x15x7mmNet weight:5g
5. Package weight:15gColor:Blue(as the picture shows)

Feature:

1. new original CH340G chips, the chips are STC official recommendation USB to TTL chips will not appear due to a different drive / different computer as a result of incompatibilities!
2. golden appearance, quality and upscale yellow pin, pin durable than the black market, beautiful;
3. not only have the power light PWR, TXD and RXD LEDs also reserved RTS, CTS location convenient and intuitive know whether the product is at work in the absence of the instrument case;
4. 3V3 and 5V by a short circuit risk selection;
5. support WINDOWS 98 / ME / 2000 / XP / Server 2003 / VISTA /
6. Server 2008 / Win7 / Win8 32 Bit / 64
7. Includes 3 state lamps.TTL level 5V/3v3 can be freely selected.

• Built-in USB to TTL Transfer chip.
• Designed to be used for USB to TTL electronic projects.
• TTL interface output, easy to connect to your MCU.
• Status LED.
• Dual 3.3V and 5V Power output, work with 3.3v and 5v target device.
• Server 2008/Win7/Win8 32 bits / 64 bits.

CH340G USB to TTL upgrade small plate

• 5V microcontroller connected to the small board of 5V
• 3V microcontroller connected to the small board of 3.3V
• Microcontroller download program needs cold start
