SparkFun RS232 Shifter SMD (No DB9) Category_Display & LED/LED's Supports Ad-HocThe 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 by 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.
