This RS232 to TTL Serial Interface Module is a board with the MAX3232 transceiver integrated circuit (IC). It facilitates serial communication between TTL and RS232 ports by providing the necessary electrical signal conversion.

These TTL Converter Module DB9 Connector boards usually have a DB9 connector soldered at one end, and four header pins with jumper cables at the other end. The jumper cables enable the user to connect the wires to a breadboard or a microcontroller project board, whilst the DB9 connects directly to a COM port of a computer. The MAX3232CSE+ IC, which comes in a 16 pin narrow SO package. It requires between 3.0 V to 5.5 V to operate and has two receivers and two transmitters. It has a maximum guaranteed data rate of 120 kbps, and the circuitry requires four 0.1µF charge-pump support capacitors.

RS232 to TTL Serial Interface Module Kit is also compatible with the famous MAX3232 IC pins. These boards connect to systems with a UART hence, they work with ATMEL and PIC microcontrollers. This MAX3232 RS232 Serial Port To TTL Converter Module DB9 Connector 5V RS232 to TTL + Female Serial TTL + serial modules / Brush board. This module can be used to the serial port of the microcontroller module expand DVD, router, hard drive, and other equipment to upgrade.

Works like a charm.

Works like a charm.

Works perfectly with an Arduino Micro to control a projector

With Prime this came next day delivery.Used this to convert from the Arduino TTL to RS232 of a NEC projector. worked effortlessly.

Nathaniel Hatley

It works with excellent performance!

Just works

Works as advertised.No fuss or drama.LEDs showing Rx and Tx were very useful.
