This product is based on CH340G chip design , CH340G has an external crystal oscillator, clock accuracy is guaranteed.
Download this relies on the STC microcontroller serial clock timing adjustment is suitable for precision applications ,
compatibility and stability are also a large number of application development .
1, the main chip for CH340G, generate a virtual serial port driver after installation
2, USB to take power , leads to the interface includes GND, 3.3V, TX, RX, CTS, RTS signal pin level is 3.3V, positive logic
3, the board status indicators , send and receive lights, right after installing the driver status indicator lit , transceiver indicator flashes when communication baud rate higher brightness lower
Onboard five LED indicators , D1 ( power indicator ), D2 (TX status ), D3 (RX state ), D4 (CTS state ), D5 (RTS state ) ;
4, supports baud rates from 300bps ~ 1Mbps between
5, the communication format support:
A ) 5,6,7,8 data bits ;
Support 1.5, 2 stop bits ;
odd, even, mark, space, none parity
6 Supported operating systems : windows vista / xp / server 2003/200, Mac OS-X/OS-9, Linux
7 , on-board power conversion chip LM1117-3.3 , the maximum possible power output 400Ma ;
8 , full-speed USB device interface , compatible with USB V2.0
9, the software is compatible with CH341, CH341 can be used directly drivers
