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 ST232 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.

Initial kits will include a PCB that has +5V printed, but you can use any regulated DC voltage from 3V to 5.5V.

Features

• Includes MAX3232 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
• Signals: RX - TX - RTS - CTS (RTS & CTS available in V6 boards)
• Board Dimensions: 33 x 33 mm
• Ready to assemble KIT
• Schematics (V6)

No RTS/CTS header installed. RTS/CTS signals not connected to the header



RTS/CTS header installed. This pin configuration passes the RTS & CTS signals directly to the header



RTS/CTS header installed. This pin configuration routes the incoming RTS signal to the CTS signal, creating a passthrough. No RTS/CTS signal is routed to the header.

There is a 4th option, which is having the RTS/CTS header installed, and RTS signal connected to CTS on both sides of the conversion (TTL side, RS232 side).
