About this product

A simple USB to serial converter with selectable voltage through a jumper. Specifications:

With the supplied jumper you can configure the module for 5V or 3.3V. Without the jumper, the module is automatically powered with 3.3V. For 5V you have to put the jumper between the Vcc and 5V.

If you want to change the voltage, first disconnect it from a computer so that there is no voltage on the module.

Note: Users report that the driver for Mac on both old and new computers may be unstable, read this extra link to get it working. In addition, no drivers need to be installed for MacOS Mojave, these are already present.
