USB to 4th Road TTL serial port Original FT4232HL chip USB to multi -road serial port 5V 3.3V

feature:

● Carefully optimized circuit, the communication rate is as high as 12Mbps

● TTL compatible 5V level

● Drive DC 5V power interface, 500mA current output, improve the load capacity.

● Erom, can be configured as jrag/SPI and other interfaces through FT PROG software.

● All available IO export.

● Each serial port has an independent receiving and receiving indicator LED, which is convenient for observing the serial port status

● Shen Jin PCB, lead -free process, install screw holes with M3

● The four serial ports are connected at the same time, and the data can be observed at the same time.

parameter:

Power supply voltage: power supply (5.0V)

Current: 50mA

Potter rate: 1200-921600

Transmission rate: 12Mbps

Work temperature: -40-85 degrees

Interface description:

VCC: Power (5.0V)

RXD: The receiving pin of the module comes with port (TTL level, you cannot directly connect the RS232 level!)

TXD: The receiving pin of the module comes with port (TTL level, you cannot directly connect the RS232 level!)

GND: ground

Pin function:

Normal communication must be connected:

1. USB interface: Connecting the computer or host, you must connect.Dial the power selection switch to the V-USB side and get the power from USB.

2.TX A/B/C/D: serial data transmission pins (referring to the data of the module itself →, corresponding to the RX. Data reception of the external device.)

3. RX A/B/C/D: serial data receiving pin (referring to the data input ← of the data in the module itself, corresponding to the tx. Data transmission of external devices.)

4. GND: Powerland (GND must be connected, you cannot connect the error, otherwise you may damage the device or serial port module)

The following pins are not necessary for communication, you can decide whether to connect according to your needs

1. IO on both sides: Including CTS/RTS/DCD/RI/DSR and other flow control pins and 5V/3.3V power supply to lead the serial port. Generally, please decide whether to connect the need for your own situation.

2. Due to the electrical characteristics, the RX pin of the IO of both sides cannot be used for communication, and can only be used to measure signals.Please use the RX on the white XH2.54 terminal.Other IO can be used normally

3. When the factory test, the TX/RX is directly connected and can be removed during the use process.
