Our USB to TTL converter provides two way serial communications signal conversion between the TTL (Transistor Transistor Logic) input/output (from a TTL device such as a PIC or Arduino microcontroller) to and from a personal computer via virtual COM port. The USB cable installs into your PCs USB port and installs as a COM port. Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port. This is ideal for connecting your TTL microcontroller serial communications to the PC. Today’s computers typically do not have RS232 ports on them anymore, this solves that issue by providing you a virtual COM port using the common USB port. This is just a bare board with no housing, you can solder you own cable onto the board and connect it to your TTL device.
Easy to install. The drivers can also be downloaded from the FTDI site. For first time installs it will install 2 drivers before its ready to operate. You should only need to do this once per PC. Once installed you can remove and reinsert the cable without having to install the drivers each time. Goto to your device manager to determine what COM port was used. Its typically the next available COM port on your PC.
