Custom FT232 Serial port module USB to TTL USB to serial port Magnetic isolation FT232RL Photoelectric isolation

Magnetic isolation USB to TTL serial port

FT232RL is equipped with magnetic isolation USB to TTL serial interface (UART/COM interface) module. The main control module is FT232RL USB chip, ADUM3201 digital isolator made by ADI Company, and Jinshengyang power isolation module, with 1000V DC isolation voltage and reliable communication rate up to 1Mbps. The USB side and TTL output side are completely isolated to ensure the security of the computer and effectively reduce interference.

The characteristics of

FT232RL master control, the industry reputation of USB chip, industrial applications of stable choice.

ADI magnetic isolation chip ADUM3201, fast speed, good waveform, power consumption is significantly lower than photoelectric isolation.

Onboard large spacing isolated power supply, no external power supply, as long as the USB interface can be used.

Increase isolation clearance, PCB slotting, better avoid creepage, improve safety performance.

Integrated protection diode, improve protection ability.

Usb-a male interface, no cable, directly into the COMPUTER USB port can be used.

The communication level can be easily switched to 5V or 3.3V by jumper cap.

VCC output voltage can output 5V/3.3V, communication level and VCC voltage can be the same or different.

TX through reverse diode leads to independent TX-D(open leakage output), convenient connection to burn STC MCU.

Onboard power supply, send and receive three LED indicators.

Typical applications

Isolation usB-to-TTL serial port communication and debugging under high voltage danger

Upgrade the firmware of peripherals such as routers and set-top boxes

Burn (download) single-chip program

High-speed USB UART communication (up to 2Mbps)

Built into the product to improve communication reliability
