This is a USB Serial Adaptor. Using jumper wires it can be used for Arduino programming (using RTS for reset) or similar boards.

The board uses through-hole connections on both the micro-USB and 6-way 0.1" header socket for a more robust product over the surface mount alone.

This module can only be used with systems using 5V, connecting to those using higher/lower voltages may result in damage. Click here for a 3.3V version.

The IC used in the module enumerates as a Communication Device Class (CDC) device which modern (Win10/Linux/Mac OS X) operating systems have built-in drivers for.
