# Maia SDR



[Maia SDR](https://maia-sdr.org) is an open-source FPGA-based SDR project focusing on the [ADALM

Pluto](https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm-pluto.html).



It currently provides a firmware image for the Pluto with the following functionality:

* Web-based interface that can be accessed from a smartphone, PC or other device.

* Real-time waterfall display supporting up to 61.44 Msps (limit given by the

AD936x RFIC of the Pluto).

* IQ recording in [SigMF format](https://github.com/gnuradio/SigMF), at up to

61.44 Msps and with a 400 MiB maximum data size (limit given by the Pluto RAM

size). Recordings can be downloaded to a smartphone or other device.



See [maia-sdr.org](https://maia-sdr.org) for more details.



## Installation and supported hardware



See the [installation instructions](https://maia-sdr.org/installation/).



## Firmware images



Stable releases of firmware images for the ADALM Pluto and Pluto+ can be found

in the [plutosdr-fw](https://github.com/maia-sdr/plutosdr-fw) repository. See

also the [installation instructions](https://maia-sdr.org/installation/).



Development ADALM Pluto firmware images for each commit and pull request are

built automatically with Github's actions system. To download the firmware image

for the latest commit in the `main` branch (or for any other commit), click on

the actions check, then go to the `plutosdr-fw` action details, click on the

summary, and download the `pluto-firmware` artifact. This procedure is

illustrated by the following screenshots.

For each pull request, a firmware image is also built. The bot adds a comment to

the pull request with a link to the firmware when it is ready.



## Support



Support for Maia SDR is handled through

[Github issues](https://github.com/maia-sdr/maia-sdr/issues)

and

[Github discussions](https://github.com/maia-sdr/maia-sdr/discussions).



## Project structure



The project is divided into the following components:



* [maia-hdl](maia-hdl). The FPGA design. It is written in

  [Amaranth](https://github.com/amaranth-lang/amaranth). It can be used to build

  the Vivado project and bitstream for Maia SDR or as a library in other projects.

* [maia-httpd](maia-httpd). The software application that runs on the Zynq ARM CPU.

  It is written in asynchronous Rust and spawns a web server.

* [maia-kmod](maia-kmod). A kernel module used to control some RAM buffers that

  are used to exchange data between the FPGA and CPU.

* [maia-wasm](maia-wasm). A web application that is the UI of Maia SDR. IT is

  written in Rust with WebAssembly and uses WebGL2 to render the waterfall.
