prolific usb to serial comm port use with arduino

Used as ordinary USB to serial TTL module, downloading STC microcontroller. The COM port the user should take note of is that which is labeled Prolific USB-to-Serial Comm.With the serial communication level selection of 3.3V and 5V.With power, sending and receiving indicator light easily check the working status.

Original FT232 chip, stable performance.Standard interface, compatible with a variety of Arduino official controllers.The module has a standard interface, compatible with various Arduino official controllers, such as arduino pro mini. Throw out the overhead of the + and -15v, limit or leave out the handshake signals, (mis)use the DTR signal to reset the Arduino, use it to download firmware or. The module has a DIP switch used to control the serial communication voltage for 3.2V or 5V. This is a USB to serial module, using the FT232RL chip. Many manufacturers have the production of such chips, such as the CP210x series of Silicon LABS, TI's TUSB3410, CH34x series of Nanjing Qinheng, FT232 series of FTDI, Prolific’s PL230x series, Echo's ARK3116 and so on.įrom the perspective of stability, FT232 series is the most reliable, and you can use it to debug the procedures without worrying about the blue screen. With the development of computer technology, parallel port and serial port on the PC slowly disappeared, and now even the desktop are few parallel.īut for engineers, parallel port and serial port are essential interfaces, especially the serial port.įor those computers without serial port, the most convenient solution is to use a USB to serial chip to virtual a serial port out.
