Product Description
The smallest and easiest to use serial conversion circuit on the market! This board has one purpose in life - to convert RS232 to TTL and vice versa (TX and RX). This will allow a microcontroller to communicate with a computer. Shifter SMD is powered from the target application and can run at any voltage! That's right - 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. Dimensions: 1.25 x 1.15"

Rx & Tx Switched

Reviewer: from MOAB, UT USA

This little unit works like a champ once you understand that it is mis-labeled. "PC talks on pin 3 of DB9" That is the line that is connected to the Rx line of your MCU. The Tx line of the your MCU goes thru the device and talks on pin 2 of the DB9. The schematic and the pcb are both labeled wrong.
