USB to RS232 Converter Circuit FT232RL
Especially RS232 serial port that you can use in notebook computers are not made with FT232RL SMD circuit converter USB/RS232 USB to RS232 converter circuit sizes are quite small except socket SMD other materials used in small type
The suitability of any electronics RS232 no need to convince. The problem is that all new computers have only USB and COM ports, LPT, or even a PS / 2 hard to find. However, all is not lost! By compositions FT232RL adapter can easily be done with a USB to RS232, RS422, RS485, and besides układzik can perform several unusual operations.
