## Overview

The NOYITO TTL to RS232 Module is a compact, high-quality serial level converter designed for seamless communication between TTL devices (MCU, ARM, FPGA, Arduino) and RS232 level equipment. Supporting a wide 3-5.5V power range and offering both male and female RS232 ports, it features 15KV ESD protection and includes six DuPont wires for easy integration. Its clearly labeled pins and printed schematic empower professionals to deploy reliable serial communication with confidence.

## Description

Uses： The TTL serial port of the MCU, ARM, FPGA, Arduino, etc. communicates with the RS232 level device. Serial expansion of the device. RS232 port communication with computer PC. Can be used for GPS, electronic compass, car detection, hard disk maintenance etc .(Need the user staff with a certain degree of professional knowledge and operational capabilities) Description: Supports 3-5.5V power supply. RS232 can choose male or female. The package contains six DuPont wires. Use high-quality chips. In order to facilitate the use of the product, each pin is marked, and a schematic diagram of the product is printed on the back of the product. Instructions for use: (Taking the access MCU as an example, how to connect each row of pins) TTL (UART) side: VCC: DC 3V-5.5V GND: Connect to GND TXD: Connect to MCU.RX (Signal Flow: MCU.RX ← SP3232 ← RS232.TX ) RXD: Connect to MCU.TX (Signal Flow: MCU.TX → SP3232 → RS232.RX) CTS, RTS is not used by default. RS232 side: RXD: Connect RS232.TX (Signal Flow: RS232.TX →SP3232 → MCU.RX) TXD: Connect to RS232.RX (Signal Flow: RS232.RX ← SP3232 ← MCU.TX) GND: Connect to RS232.GND CTS, RTS is not used by default. Package Included: 1 pcs TTL to RS232 Module

Review: This seems to be a quality TTL to RS232 module. It works well with Raspberry Pi. The 3232 chip appears to be a Sipex SP3232EEN, which based my understanding, is now being produced by MaxLinear. I did not verify functionality for use with hardware flow control, but the CTS and RTS pins are available on the TTL side and every pin on the DB9 connector is soldered to the board. Even the jumpers that came with the module are good quality! Very straightforward to use.

This adapter actually works, and works well. Not a knock off chip. Great for giving a Raspberry Pi, or ESP32 a DB9 serial port. The signal voltage conversion is very reliable.
