# USRP Hardware Driver (UHD™) Software
Welcome to the UHD™ software distribution! UHD is the free & open-source
software driver and API for the Universal Software Radio Peripheral (USRP™) SDR
platform, created and sold by Ettus Research.
UHD supports all Ettus Research USRP™ hardware, including all motherboards and
daughterboards, and the combinations thereof.
## Documentation
For technical documentation related to USRP™ hardware or UHD system
design, check out the UHD and USRP Manual.
That is where you can find
Installation Instructions,
help on how to
build UHD from source on
different platforms, development guidelines and reference documentation as well
as device usage guidance.
Additionally, be sure to check out the Ettus Research
FAQ, and the
Knowledge Base for useful application notes and
tutorials.
## OS Support
UHD is primarily developed on Linux, but we also test and support the following
operating systems.
* Linux (Fedora and Ubuntu)
* Mac OS X
* Windows 11
Other operating systems will most likely work, too, but are not officially
supported.
## Applications
UHD can be used to build stand-alone applications with USRP™ hardware, or with
third-party applications. Some common toolkits / frameworks are:
* GNU Radio
* RFNoC OOT Blocks
* NI LabVIEW - UHD RFNoC
* NI LabVIEW
* MathWorks Matlab and Simulink
* REDHAWK
* OpenBTS GSM
* Osmocom GSM
* Amarisoft LTE
* Software Radio Systems srsRAN
* Eurecom OpenAirInterface
## Directories
