This module enables you to add serial communication signal conversion between RS232 serial COM port and TTL output to your project. It can be used on any systems with UART that means it can connect to Atmel and PIC microcontrollers like Arduino.
The module is easy to use, you can connect the module to microcontrollers through the pins and the DB9 end to a COM port of a computer and program it. The specifications tell more of the board capabilities:
- Operating Voltage 3.3V – 5V DC
- Working Current: 6mA
- Power Supply: External
- Pins: TXD, RXD, GND, VCC
