Ready to embark on your journey with Edge Impulse? Follow these essential steps to get started:
Start by creating your Edge Impulse account. Registration is straightforward, granting you immediate access to the comprehensive suite of tools and resources.
Upon logging in, initiate your first project. Select a name that resonates with your project's objectives. If you already which hardware target or system architecture you will be using, you can set it up directly in the dashboard's project info section. This will help you to make sure your model fits your device constraints.
We offer various methods to collect data from your sensors or to import datasets (see Data acquisition for all methods). For the officially supported hardware targets, we provide binaries or simple steps to attach your device to Edge Impulse Studio and collect data from the Studio. However, as an embedded engineer, you might want to collect data from sensors that are not necessarily available on these devices. To do so, you can use the Data forwarder and print out your sensor values over serial (up to 8kHz) or use our C Ingestion SDK, a portable header-only library (designed to reliably store sampled data from sensors at a high frequency in very little memory).
Edge Impulse offers an intuitive model training process through processing blocks and learning blocks. You don't need to write Python code to train your model; the platform guides you through feature extraction, model creation, and training. Customize and fine-tune your blocks for optimal performance on your hardware. Each block will provide on-device performance information showing you the estimated RAM, flash, and latency.
This is where the fun start, you can easily export your model as ready-to-flash binaries for all the officially supported hardware targets. This method will let you test your model on real hardware very quickly.
In addition, we also provide a wide variety of export methods to easily integrate your model with your application logic. See C++ library to run your model on any device that supports C++ or our guides for Arduino library, Cube.MX CMSIS-PACK, DRP-AI library, OpenMV library, Ethos-U library, Meta TF model, Simplicity Studio Component, Tensai Flow library, TensorRT library, TIDL-RT library, etc...
The C++ inferencing library is a portable library for digital signal processing and machine learning inferencing, and it contains native implementations for both processing and learning blocks in Edge Impulse. It is written in C++11 with all dependencies bundled and can be built on both desktop systems and microcontrollers. See Inferencing SDK documentation.
Building Edge AI solutions is an iterative process. Feel free to try our organization hub to automate your machine-learning pipelines, collaborate with your colleagues, and create custom blocks.

Now that you have a roadmap, it's time to explore Edge Impulse and discover the exciting possibilities of embedded machine learning. Let's get started!
Welcome to Edge Impulse! Whether you are a machine learning engineer, MLOps engineer, data scientist, or researcher, we have developed professional tools to help you build and optimize models to run efficiently on any edge device.
In this guide, we'll explore how Edge Impulse empowers you to bring your expertise and your own models to the world of edge AI using either the Edge Impulse Studio, our visual interface, and the Edge Impulse Python SDK, available as a pip package.
Flexibility: You can choose to work with the tools they are already familiar with and import your models, architecture, and feature processing algorithms into the platform. This means that you can leverage your existing knowledge and workflows seamlessly. Or, for those who prefer an all-in-one solution, Edge Impulse provides enterprise-grade tools for your entire machine-learning pipeline.
Optimized for edge devices: Edge Impulse is designed specifically for deploying machine learning models on edge devices, which are typically resource-constrained, from low-power MCUs up to powerful edge GPUs. We provide tools to optimize your models for edge deployment, ensuring efficient resource usage and peak performance. Focus on developing the best models, we will provide feedback on whether they can run on your hardware target!
Data pipelines: We developed a strong expertise in complex data pipelines (including clinical data) while working with our customers. We support data coming from multiple sources, in any format, and provide tools to perform data alignment and validation checks. All of this in customizable multi-stage pipelines. This means you can build gold-standard labeled datasets that can then be imported into your project to train your models.
In this getting started guide, we'll walk you through the two different approaches to bringing your expertise to edge devices. Either starting from your dataset or from an existing model.
First, start by creating your Edge Impulse account.
Start with existing data
You can import data using Studio Uploader, CLI Uploader, or our Ingestion API. These allow you to easily upload and manage your existing data samples and datasets to Edge Impulse Studio.
We currently accept various file types, including .cbor, .json, .csv, .wav, .jpg, .png, .mp4, and .avi.
If you are working with image datasets, the Studio uploader and the CLI uploader currently handle these types of dataset annotation formats: Edge Impulse object detection, COCO JSON, Open Images CSV, Pascal VOC XML, Plain CSV, and YOLO TXT.
Organization data
Since the creation of Edge Impulse, we have been helping our customers deal with complex data pipelines, complex data transformation methods and complex clinical validation studies.
The organizational data gives you tools to centralize, validate and transform datasets so they can be easily imported into your projects.
See the Organization data documentation.
To visualize how your labeled data items are clustered, use the Data explorer feature available for most dataset types, where we apply dimensionality reduction techniques (t-SNE or PCA) on your embeddings.
To extract features from your data items, either choose an available processing block (MFE, MFCC, spectral analysis using FFT or Wavelets, etc.) or create your own from your expertise. These can be written in any language.
Similarly, to train your machine learning model, you can choose from different learning blocks (Classification, Anomaly Detection, Regression, Image or Audio Transfer Learning, Object Detection). In most of these blocks, we expose the Keras API in an expert mode. You can also bring your own architecture/training pipeline as a custom learning block.
Each block will provide on-device performance information showing you the estimated RAM, flash, and latency.
Start with an existing model
If you already have been working on different models for your Edge AI applications, Edge Impulse offers an easy way to upload your models and profile them. This way, in just a few minutes, you will know if your model can run on real devices and what will be the on-device performances (RAM, flash usage, and latency).
You can do this directly from the Studio BYOM feature or using Edge Impulse Python SDK.
Edge Impulse Python SDK is available as a pip package:
From there, you can profile your existing models:
And then directly generate a customizable library or any other supported deployment type
You can easily export your model in a .eim format, a Linux executable that contains your signal processing and ML code, compiled with optimizations for your processor or GPU. This executable can then be called with our Linux inferencing libraries. We have inferencing libraries and examples for Python, Node.js, C++, and Go.
If you target MCU-based devices, you can generate ready-to-flash binaries for all the officially supported hardware targets. This method will let you test your model on real hardware very quickly.
In both cases, we will provide profiling information about your models so you can make sure your model will fit your edge device constraints.
If you want to get familiar with the full end-to-end flow using Edge Impulse Studio, please have a look at our end-to-end tutorials on continuous motion recognition, responding to your voice, recognizing sounds from audio, adding sight to your sensors, or object detection.
To understand the full potential of Edge Impulse, see our health reference design that describes an end-to-end ML workflow for building a wearable health product using Edge Impulse. It handles data coming from multiple sources, data alignment, and a multi-stage pipeline before the data is imported into an Edge Impulse project.
While the Edge Impulse Studio is a great interface for guiding you through the process of collecting data and training a model, the edgeimpulse Python SDK allows you to programmatically Bring Your Own Model (BYOM), developed and trained on any platform:
Expert mode (access Keras API in the studio)
NVIDIA TAO Toolkit (access state-of-the-art pre-trained models)
