The Expanded UART to USB Module add selectable I/O voltage for convenience in working with todays low voltage embedded systems and microcontrollers. Unlike traditional UART to USB modules, this unit has built in voltage level shifting, allowing direct interfacing to low voltage interfaces. The added options for flow control and GPIO control make this an indispensable tool for developers.

A small form-factor module that monitors voltage and current. Report measurements over its flexible sercom serial interface and can be configured to visually alert when certain conditions occur.
