RS232 to TTL Converter Module

This module can be utilized to change over the RS232 voltage of PC to TTL voltage utilized by the microcontroller. Straightforwardly plug the DB9 connector into your PC then you can speak with the microcontrollers utilizing the Serial port. It is relevant to an assortment of stages including Arduino/AVR/ARM. For Arduino, if it’s not too much trouble, likewise note that there is as of now a UART2USB association, you simply need this module on the off chance that you need more sequential association with your PC.

The RS232 serial port to TTL converter module is a board with the MAX3232 transceiver integrated circuit (IC), which facilitates serial communication between TTL and RS232 ports by providing the necessary electrical signal conversion. These boards usually have a DB9 female connector soldered at one end, and four header pins with jumper cables at the other end.
