Product Description

Tired of Machine freezes because of USB dropout? If you have a PC with on-board serial lying around, why not interface your UNO with Straight Serial connection.

You’ll need a 12V power supply for the UNO, The RS232 to TTL converter and a Serial cable.


About the Board:

This board has one purpose in life – to convert RS232 to TTL and vice versa (TX and RX). This will allow a micro-controller to communicate with a computer. Power the board at 5V and the unit will convert RS232 to 5V TTL. Power the board at 2.8V and the Shifter board will convert RS232 to 2.8V CMOS TTL. Includes two indicator LEDs for TX and RX. Runs from 300bps up to 115200bps.
Unit comes fully assembled and tested as shown. You can either solder a 4-pin header or individual wires
