The SerialComm TTL-232-33P is a compact bi-directional RS-232 to 3.3V TTL serial converter designed to interface standard RS-232 serial devices with 3.3V TTL-level UART equipment such as embedded systems, microcontrollers, GPS receivers, and development boards. It is port-powered, requiring no external power supply in most applications.
