This USB to TTL adapter is based on the PL2302 USB to TTL serial converter IC. It is commonly used when microcontrollers like Arduino, Raspberry Pi, PIC, etc. have to communicate with computers through serial communication. USB has DATA lines D+ and D- that can be connected and routed by CMOS switches. The USB can be connected to many peripheral devices and has a very fast speed of data transfer also it is used with Windows, Mac, or any other operating system. On the other hand, Arduino works on the UART data transfer protocol i.e. TTL logic level data transfer protocol, it only works on 0V or 5V logic levels. That is why we need a USB to TTL serial converter IC so that Arduino or any other controller which works on the UART protocol can be connected to the computer. It can also be used to program and or communicate with a GPS/GSM module through AT commands. The module supports both 3.3V and 5V interface.
- Stable and reliable chipset PL2302.
- USB specification 2.0 compliant with full-speed 12Mbps.
- Standard USB type A male and TTL 6pin connector.
- 6pins for 3.3V, RST, TXD, RXD, GND & 5V.
- All handshaking and modem interface signals.
- Baud rates: 300 bps to 1.5 Mbps.
- Hardware or X-On/X-Off handshaking supported.
- Temperature Range: -40 to +85.
If you want to connect it to Arduino nano pro or any other microcontroller, you need to plug the USB A male connector in the USB port of your PC, then connect TX, RX, DTR, GND, and 5V to the respective pins of the controller, you are using and make sure you have selected the correct BAUD rate that your controller supports. Also, download the PL2302 IC Drivers on your PC.
