title: RS-232 To TTL Conveter (MAX3232IDR) category: Grove bzurl:

oldwikiname: prodimagename: surveyurl: sku: 103990363 tags:

Most of the MCUs use TTL levels, and the computer serial port generally uses 232 levels. If we want the

computer to communicate with the MCU, we need this RS-232 To TTL Conveter (MAX3232IDR).

This module is based on Max3232, it supports multiple baud rate communication and theoretically supports

communication up to 230400bps baud.

Feature

Easy to use

Stable, high speed

High cost performance

±15-kV ESD Protection

Low power consumption

Two Drivers and Two Receivers

Getting Started This is a simple module that only needs to connect the corresponding interface to the corresponding device to transfer data using the serial port tool. You should note that when connecting a TTL device, the RX pin of the module needs to be connected to the TX pin of the device, and vice versa, the TX pin of the module needs to be connected to the RX pin of the device.
