Multi Voltage USB to USART Converter board
This USB-2-USART module is designed to quickly adapt to any USART interfaced device/module
This USB-2-USART module is designed to quickly adapt to any USART interfaced device/module (example: USART based Video/Still cameras, WiFi Modules, Blue tooth Modules, RF Communication Modules, etc) without putting too much effort in rigging hardware. This module also helps to quickly start software/driver development for USART based modules in any embedded electronic system.

We developed this product for our in-house requirements, to quickly evaluate any sensors/devices or modules which have a USART interface. In the process, we thought up of features and interfaces that would reduce the time to quickly rig up a USB-2-USART interface to any electronic modules that we buy off the shelf. And we realized this module maybe of use to any embedded/electronics professionals to accelerate their electronic design and embedded software development cycles.

Driver installation on Linux

Note: Recent versions of the Linux kernel include support for the CP2102 USB-to-USART Bridge Controller as part of the usb-serial driver, so your CP2102 USB 2 USART Module should work right out of the box.

For other variants of Linux other than Ubuntu, the Linux package can be found at this link.
