MAX232 Module RS232 to TTL Converter Module

MAX232 Module RS232 to TTL Converter Module can be used to convert the RS232 voltage of PC to TTL voltage that used by microcontroller. Directly plug the DB9 connector your PC then you can communicate with the microcontrollers using the Serial port.

It is applicable to a variety of platforms including Arduino / AVR / ARM. For Arduino, please also note that there is already a UART2USB connection, you just need this module if you want more serial connection to your computer.

This MAX232 Module RS232 to TTL Converter Serial Interface Module is a board with the MAX3232 transceiver IC. It facilitates serial communication between TTL and RS232 ports by providing the necessary electrical signal conversion. Use the RS232 to TTL converter to communicate from a teensy 2.0 to display on a computer terminal program via an RS232 port.

The RS232 to TTL converter module widely uses in radio modifications, phone flash, XBOX360 flash, GPS, vehicle detection, DVD flash, hard disk repair set-top box upgrade. It can be used to program STC MCU, NXP MCU, Renesas MCU, STM32 MCU, N+-2EC MCU.

This converter can connect to an Arduino Serial pin (0,1) to convert standard Arduino TTL to RS232. It allows Arduino talk to hundreds of RS232 devices.

The MAX232 Module to Transistor-Transistor Logic (TTL) Serial Port Converter Module is used to stabilize a Serial Communication between TTL and RS-232 ports. Most Microcontrollers these days have built-in Universally Asynchronous Receiver/Transmitter (UARTs) that can be used to receive and transmit data serially. The MAX3232 Module has a MAX3232 IC, that facilitates serial communication between a computer and a microcontroller.
