Description
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.

Features

  • Includes ICL3232 or compatible IC with Capacitors
  • Supports 3V to 5.5V (based on regulated DC voltage supplied to the board)
  • DB9 Female Connector (RS-232)
  • Standard Header Connector (TTL)
  • Suitable for use with most microcontrollers
  • 300 to 115200 bauds
  • Board Dimensions: 32 x 37 mm
  • Pre-assembled board

Version 7 board offers 2 jumpers (J1, J2) to control RTS/CTS signals. You can use the included jumpers to set different configurations. If no jumpers are installed, the RTS/CTS signals are ignored.

I bought 2 of these to connect a pair of TTL interface data radios to PC serial ports. They worked perfectly. The build quality is high. They have the RTS and CTS lines which other boards do not have. I need the CTS line so these work out well. They arrived quickly. I am quite happy and would recommend these to others. Randy K8KWL

Questions and Answers
Q: When I put 3V to Vcc, the Tx LED illuminates red. Is that correct?
Asked by: LJJowers - 8/6/2014 (Submit an answer)
A: This board does not have TX/RX LEDs. If you are asking about the RS232 to TTL DTE adapter, then yes, it is normal for TX/RX LEDs to illuminate randomly at the beginning, when it is powered up and no signal is available on the RS232 side, as it is floating without a specific state LOW or HIGH.
