## Overview

This 2-piece mini MAX3232 RS232 to TTL converter breakout board supports 3V to 5V logic levels, enabling seamless communication between low-voltage microcontrollers and RS232 devices. With a compact 18.4x27.9mm footprint, it delivers up to 120kbps baud rate, built-in ESD protection, and includes all necessary capacitors and terminal blocks for quick, reliable integration in professional and hobbyist electronics projects.

## Description

Specification: Dimensions：18.4*27.9mm（0.73*1.1） MAX3232 voltage range: 3V-5V Maximum baud rate: no more than 120kbps Package Includes: 2*mini RS232 to TTL MAX3232 breakout board 2*Terminal bloock

## Features

- This is an RS232 converter IC capaable of operating at 3V and communicating with 5V logic for TTL/CMOS projects.
- We use the SOIC package MAX3232 and disconnected all the pins needed to set the RS232 to TTL connection. And it includes the necessary five 0.1uF charge pump capacitors.
- Even when operating at a high data rate, MAX3232 can still maintain the minimum transmitter output voltage of ±5.0V required by the RS-232 standard.
- The chip has ESD protection function, supports flow control, and zero-delay automatic transmission and reception conversion. It worked like a charm and converts the signals to the proper levels.
- MAX3232 transceiver breakout board，which can replace MAX232 to complete the matching of 5V system and RS232 high-voltage interface, and also realize the interconnection of 3V low-voltage system and RS232 interface.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works great
  

*by J***M on Reviewed in the United States on 27 September 2023*

Used this on an Esp32 project to monitor a solar controller via modbus rs232. Need to solder the connectors on or wires directly to the board. They do not come soldered on. Works great. Will buy again if I need to make another one

    Haben bei mir nicht funktioniert?
  
  

*by G***. on Reviewed in Germany on 19 March 2024*

Ich weiß nicht, was los war, aber die haben bei mir nicht funktioniert.Zumindest habe ich aus einer RS232 Quelle keine TTL Signal bekommen.Vielleicht lag es an mir, aber ich musste die zurückschicken.

    Quality Product and Compact Size
  

*by E***H on Reviewed in the United States on 22 February 2023*

Bought this for a project needing RS232 control with an RPi. The Treedix board is tiny and with soldered-on leads it is small enough to easily tuck inside a regular RPi case, just add a tiny strip of electrical tape to cover the back-end of the leads. I added a 3 pin terminal block to the case for the external plug and ran the RS232 leads to that and mapped the Logic leads to GPIO.  Much better than the giant DB9 interface most adapter boards come with. I am buying an extra set just to keep in the project parts drawer.
