This "Shifter SMD" board converts RS232 to TTL and vice versa (TX and RX). This will allow a microcontroller to communicate with a computer. The board 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 unit will convert RS232 to 2.8V CMOS TTL.
The board includes two indicator LEDs for TX and RX. It runs from 300bps up to 115200bps. The unit comes fully assembled and tested. You can either solder a 4-pin header or individual wires.
Dimensions: 1.25 × 1.15"
