FT232RL FTDI USB to TTL Serial Converter Module 5V and 3.3V

Description

What it is

The FT232RL FTDI module is a converter that allows communication between a USB device and a TTL (Transmitter-Receiver Logic) device. Essentially, it translates the USB signal into a TTL signal, enabling the connection of serial devices to a computer.

Features

• USB to TTL Converter
• FTDI chip FT232RL
• 5V and 3.3V Power Supply
• SKU: ARD006403
• Price: 6.51 €

What it is for

The FT232RL module is ideal for connecting serial devices, such as Arduino and other microcontrollers, to a computer. It can be used for:
– Creating simple serial interfaces to control LEDs, motors, or other devices via a computer.
– Transmitting data between a computer and a serial device.
– Programming microcontrollers via a computer.

Tutorial: How to Use FT232RL FTDI USB to TTL Serial Module 5V and 3.3V

The FT232RL converter is essential for connecting serial devices to a computer. Ideal for beginners and intermediates working with Arduino and other microcontrollers.

What you need

• FT232RL FTDI Converter
• Arduino or microcontroller serial
• USB cable
• Soldering station (optional)

Steps

1. 1. Check that the converter has the following pins: VCC, GND, TXD, RXD.
2. 2. Connect the VCC of the converter to the 5V of the Arduino.
3. 3. Connect GND of the converter to GND of the Arduino.
4. 4. Connect TXD of the converter to RXD of the Arduino.
5. 5. Connect RXD of the converter to TXD of the Arduino.
6. 6. Connect the USB cable to the converter.
7. 7. Start the Arduino IDE program.
8. 8. Load the ‘Serial Monitor’ example code onto the Arduino.

Example code

void loop() {}

Mini project

Create a simple serial interface to control an LED with the press button.

Common mistakes

• Do not connect the TXD and RXD pins correctly.
• Forget to activate the serial in the code.
• Connect the VCC to the 3.3V instead of the 5V.
• Do not have the FTDI driver installed.

Recommended accessories

• Arduino Uno
• LED
• 220 Ohm resistor
• Push button
• USB cable

Frequently asked questions

How can I check if I have the FTDI driver installed?
Open the Device Manager and look for ‘FTDIBUS’.

Can I use this converter with a 3.3V microcontroller?
Yes, but make sure the converter supports 3.3V.

Which pins of the converter should I use for a 3.3V microcontroller?
Connect VCC to 3.3V, GND to GND, TXD to RXD, RXD to TXD.

I lost the USB cable, can I use another one?
No, make sure you have the specific FTDI USB cable.
