## Overview

The MAX232 RS-232 MAX3232 to Serial UART TTL Voltage Converter Module by UPGRADE INDUSTRIES is a high-performance solution designed for seamless data communication. With a supply voltage range of 3.3V to 5V and a maximum speed of 115200 Kbps, this compact module is perfect for various applications, ensuring reliable and efficient data transfer.

## Description

This device converts TTL to RS232 levels. It will allow you to connect a TTL serial line from a microcontroller or computer (like an Arduino using TTL output at 0 to 5V) to an RS232 bus. This chip adjusts itself to the line level voltage of the RS232 bus and then converts that down to TTL levels for small devices like microcontrollers.

## Features

- Supply voltage: 3.3 - 5V
- MPN: MAX3232
- Max Speed: 115200 Kbps - may run faster at different voltages
- Datasheet: Datasheet
