Today i received in my mail box the µUSB-CE5 from 4Dsystems. This is a very nice and slim USB to Serial UART bridge. Some major features are: it’s cost effective, easy to use, small design and can plug directly on USB port without need any connector.
I needed this converter to use it with: µOLED-32028-P1T - 2.83? Active Matrix OLED Module with Touch Screen
The design is based around the FT232RQ from FTDI and provides the user with multi baud rate serial data up to 3M baud rate. RX and TX signals are both 3.3V and 5V tolerant. Visit product page for more information.
