This module is used to convert RS232 to TTL and vice versa (TX and RX). This will allow a microcontroller to communicate with a computer. The module is powered from the target application and supports both 3.3V and 5V logic.
Note: The module can be powered either via VCC pin or mini-B USB connector. The mini-B USB connector is used to supply 5V to the module. It does not convert the signal from RS232 to USB.
Dimensions: 36 x 31mm
