    990.004 USB to Serial Micro Converter

    This is a very compact board for USB to TTL Serial conversion. Based on the popular and powerful FTDI FT232 chip, you can find drivers for all of the most common Operative Systems. The module works on 5.0V and 3.3V systems, pin 7, 8 and 9 are used for voltage setting. All the most used signal pins are available, a useful TX Enable pin is available for RS485 or similar networks. Two useful LEDs allow constant monitoring of the TX and RX signals, useful for fast troubleshooting. You can connect the Board in several methods, some useful headers are included in the kit. You can also solder the wires directly to the needed pins. Soldering two 9 pin headers (included) the module can be used as a 2x9 DIL chip on standard breadboards and perfboards. Simply connect the device to a computer, install the proper drivers and a virtual serial port will be available on your system.
