RS232 Breadboard Adapter with MAX232

If you work with microcontrollers, you know how useful a MAX232 chip can be. Now with our RS-I serial adapter, connecting RS-232 to your breadboard is plug and play.

You simply plug the 6 pins of the RS-I directly into your breadboard. Pin 1 and 2 require +5V (regulated) and ground. The other four pins give you access to the serial port transmit, receive, RTS, and CTS lines. The female DB-9 will connect directly to a PC with a straight cable. Perfect for connecting a second serial port to a Basic Stamp, PIC projects, or anywhere you need RS-232 connections. Works with many PIC bootloaders including our APP-II. These popular boards appear in many places around the Internet:

• Controlling a digital camera
• Feeding cats with Linux
• Distance Sensor
• RS-I board used in a PIC programmer

Although the RS-I only requires 5V (use a MAX3232 for 3.3V, not included), special circuitry in the IC generate positive and negative voltages required for true RS-232 interfacing. Operates up to 120kBaud.

Please note that this is a kit and does require soldering and basic electronic tools. This allows you to customize the board to fit your needs. All the parts are through hole, and the solder masked board is very easy to assemble. Check our store if you want an assembled unit or the bare PCB.

By default, the port is wired to connect directly to a PC (DCE) but a special hole pattern on the board allows you to easily wire it as DTE if you need to connect to a modem or other DTE device.
