RS232 to TTL converter board DTE with male DB9 3.3V to 5V
Our new RS232 Converter Board, is a quick and easy solution to adding RS232 communication to your project. The board connects directly to most standard microcontroller UART's to provide simply 2-wire communication.The board incorporates the industry standard ICL3232 for signal conversion and buffering. Suitable for standard TTL 3V to 5.5V input. This compact and inexpensive board can be used on most control systems.This version has a male DB9 connector wired in DTE mode (pin 2 = RX Input, pin 3 = TX Output, pin 5 = GND, pin 7 = RTS Output, pin 8 = CTS Input).We also added TX and RX LEDs to show blinking when there is activity on RX and TX lines.Schematics:  http://media.nkcelectronics.com/downloads/rs232ttl_DTE_v1.1.pdf
