MAX3232 RS232 to TTL Converter Module

This is a small handy module for rapid prototyping projects requiring RS232/PC interface to robotics and microcontroller based projects using 3.3V or 5V TTL logic.  This module converts signals between RS232 voltage levels and TTL voltage levels. 


Features:

  • Working voltage:3.3V-5.5V
  • Size : 30mmx20mm / 1.18''x0.78''
  • Weight 14g approx.
  • High speed, built in SMD MAX3232 device fitted.
  • Supports Data Transfer upto 115kbps or even higher in short bursts.
  • Works with PCs or Laptops.
  • Tested with microcontroller UARTs e.g. Microchip PIC16F877 and Atmel AVR (ATMEGA8515) devices.
  • Selectable +3.3V or +5V signals levels at the TTL level (single 3.3V or 5V supply required via header).
  • Status LED (D1)
  • It can be used with Microchip PIC, Atmel AVR, STC MCU, NXP MCU, Renesas MCU,STM32 MCU and many other such micros. 
  • Also used in radio modification, XBOX360 flash, vehicle detection, phone flash, GPS , hard disk repair
  • Port: TX RX VCC GND
  • Package Included:
    1PCS*MAX3232 RS232 to TTL Serial Converter Module
    4PCS*Dupont cables.

TTL Connections Pinout:


Pin 1: VCC(+) - this pin requires 3.3V (or 5V for 5V TTL logic targets) to be supplied to the board for power.

Pin 2: RX - MAX3232 ROUT1 - This is actually a TTL output - this pin is usually connected to the RX pin of the UART in a microcontroller.
PC Serial Port RS232 level converted from TTL level input

Pin 3: TX - MAX3232 DIN1 - This is actually a TTL input - this pin is usually connected to the TX pin of the UART in a microcontroller.
PC Serial Port RS232 level converted to TTL level output

Pin 4: GND - this pin is the ground pin. This pin is usually connected to the 0V rail of the application hardware. Fully assembled.
