USB UART TTL converter

USB Converter A - RS232 TTL UART output 5V 3.3V

The USB-RS232 TTL module works with 3.3 and 5V devices. The converter finds its application in places where serial port is used for communication, namely: GPS, GSM, Arduino circuits, routers, decoders. The converter is also used for programming Arduino mini microcontrollers.
