The FT232R is a USB to serial UART interfaceA low-cost way to add USB capability to microcontrollers. Use this to give your own breadboard For USB capability for bootloading or downloading sketches.RXD/TXD transceiver communication indicatorIncludes over-current protection, using a 500ma self-restoring fuseThis board includes a DTR pin needed to auto-reset when downloading to your device.USB Power Supply: 3.3V or 5VSize:43x17mmBlue FT232 moduleSupport windows8.TXD, RXD, , : Use curved pin header to lead.FT232R introduction:With the development of computer technology, parallel ports and serial ports have slowly disappeared on PCs. Nowadays, even desktop computers have few parallel ports. for engineers, both parallel and serial ports are interfaces, especially serial ports. For computers without a serial port, a convenient solution is to use a USB-to-serial chip to virtualize a serial port. Many manufacturers produce such chips, such as CP210x series from silicon LABS, TUSB3410 from TI, CH34x series from Qinheng, and FT232 series, PL230x series, ARK3116, etc. From the perspective of stability, the FT232 series is still , and you can use it to debug the without worrying about the blue screen.The FT232R chip is a single-chip solution. Generally, peripherals are not required for general use. Even the crystal oscillator, USB matching resistor, and EEPROM for product information have been integrated inside. FT232R also has some more useful functions. For details, refer to the FT232R data sheet.Colour:As shownMaterial:PC+MetalPackage Contents:5 x serial to usb adapterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
