Description

1.Description:

 It is a USB to TTL serial port.It supports 5V/3.3V/1.8V three level switching,VCC/TX/RX/RTS/CTS/DTR/DCD/RI/ can be switched.It is input via USB and output via TTL interface.

2.Feature:

 1).It uses the FT232RL main control chip,which is fast and stable.

 2).It supports Windows XP/WIN7/WIN8/WIN10 32/64 bit systems.

 3).The stable speed can reach 3Mbps (3 times of 921600).

 4).The power supply VCC and signal level (including flow control pins CTS/RTS/DTR/RI/DCD) can be freely switched between 5V/3.3V/1.8V,adapting to systems with different voltages.

 5).It has three indicator lights with integrated power supply (blue),receiving (green),and sending (red).

 6).It has a 500mA self-recovery fuse onboard,which will automatically disconnect when over-current/short-circuit,which effectively protects the computer's safety.

 7).Its power supply capability is strong,and the maximum output current is 500mA,which can drive most of the SCM system boards.

 8).It integrates protection diodes,and the signal line will not damage the module if an abnormal voltage occurs occasionally.

 9).It leads to the CTS/RTS/DSR/RI/DCD signal pins,which can facilitate hardware flow control.

 10).It is small in size and highly integrated,and only occupies the width of a USB interface,even if the USB port is very close to the computer,it will not affect the insertion of other devices.
