FT232RL is a powerful USB – to – serial chip produced by FTDI, which is widely used in various electronic design projects. With its efficient and stable characteristics, it provides developers with a convenient hardware communication solution. The FT232RL chip provides designers with a simple way to implement RS – 232 serial communication function through the USB interface. It integrates USB full – speed processing function, serial engine and FIFO buffer, without the need for an external USB interface chip or FIFO RAM. This degree of integration simplifies the design process and reduces the development cost.

Instructions for Use
- GND: Connect to GND.
- RXD: Connect to MCU.TX (Signal flow: MCU.TX >> FT232 >> PC.RX).
- TXD: Connect to MCU.RX (Signal flow: MCU.RX << FT232 << PC.TX).
- 3V3/5V: Output 3.3V or 5V (When the module is powered by USB, the jumper cap must be set to 3.3V or 5V).
- RTS: Connect to MCU.CTS (Signal flow: MCU.CTS << FT232 << PC.RTS).
- CTS: Connect to MCU.RTS (Signal flow: MCU.RTS >> FT232 >> PC.CTS).Note: (Take connecting to MCU as an example)
The FT232RL magnetic isolation USB to TTL serial interface (i.e., UART/COM) module uses the FTDI USB chip FT232RL as the main control, adopts the digital isolator ADUM3201 and a power isolation module. It has a DC isolation voltage of 1000V and a reliable communication rate of up to 1MBPS. The USB side and the TTL output side are completely isolated, which fully ensures the safety of the computer and effectively reduces interference.
Product Features

- ADI magnetic isolation chip ADUM3201, with fast speed, good waveform, and power consumption significantly lower than that of optical isolation.
- On – board large – spacing isolated power supply, no external power supply is needed, and it can be used as long as it is plugged into a USB interface.
- Increased isolation gap and PCB slotting to better avoid creepage and improve safety performance.
- Integrated protection diode to improve protection capability.
- USB – A male connector interface, no connecting wire is needed, and it can be used by directly plugging into the computer’s USB port.
- The communication level can be conveniently switched to 5V or 3.3V through the jumper cap.
- The VCC output voltage can output 5V/3.3V, and the communication level and VCC voltage can be the same or different.
- TX leads out an independent TX – D (open – drain output) through a reverse diode, which is convenient for connecting and programming STC single – chip microcomputers.
- On – board power supply, sending, and receiving three LED indicators.

Common Problems
In which environments does the USB interface need to be isolated?
The USB interface has become one of the commonly used interfaces in the daily work and life of electronic engineers and practitioners. However, as competition in the computer industry becomes increasingly fierce and product prices get lower and lower, most merchants are forced to reduce the protection of computer motherboards. This forces most enterprises to frequently come into contact with the human body and the outside world, and many times it also supplies power to external devices. External strong electricity and strong interference put great pressure on the USB port. This leads to the premature failure of USB interfaces in many computers and even motherboard damage.
- Electrical equipment with strong electricityWhen equipment with strong electricity (such as high – voltage electricity, frequency converters, motor drives, etc.) is connected to the computer’s USB port, it may burn out the USB interface. Isolation must be carried out to ensure the safety of the computer’s USB port, motherboard, and human body, which can effectively avoid damage to the USB port and personal injury.
- Electrical equipment with strong interferenceDevices such as motor drivers and frequency converters themselves generate a lot of interference. If this interference is introduced into the USB port, it may cause the computer to crash, blue screen, or become unresponsive. Communication isolation of the USB interface can be carried out through this device to prevent the computer from being interfered.
- Noise – sensitive equipmentThe computer itself is also a noise source. By isolating the USB port, high – frequency interference from the computer can be prevented from being transmitted to sensitive equipment, thereby better acquiring data, such as audio equipment, precision measurement equipment, and medical equipment.
- Ordinary electronic equipmentFor ordinary electronic equipment, isolation can effectively avoid problems such as short – circuit damage to the computer’s USB port and blue screen caused by operational errors, greatly improving operational safety.
