The Electron E1 general-purpose processor is a complete energy-efficient part built on the Fabric architecture: a spatial dataflow grid that runs your application, on-chip memory and storage, and a standard peripheral set, programmed in C and C++.

Yes, over the standard serial interfaces and general-purpose input-output you already design with. There is no proprietary bus to design around and no vendor bridge chip to add. Download the Electron E1 product brief for specifications.

No. One part covers the whole application. Control flow, program entry and the code that does not map to a dataflow graph all run on the Electron E1, so there is nothing left for a companion part to do, and nothing to move across a bus between two processors.

A programmable power management unit and wake-up controller, with efficiency, performance, low-power, sleep and deep-sleep modes.

Yes. LiteRT and ONNX models are supported through an import step that turns the model into code the effcc Compiler builds like any other source, so inference runs on the Fabric alongside the rest of your application rather than on a separate accelerator block.

You recompile and send an over-the-air update. Models and frameworks move faster than product refreshes, and a device built around a fixed inference block ages out when the model you want no longer fits it, which leaves a working fleet in the field that cannot be improved. On the Electron E1 a new model goes through the same import and build step as the first one, and the devices your customer already paid for take the new build and keep going.

The Electron E1 Evaluation Kit has four integrated current sensors covering the system rail, the 1.8 V rail, input-output, and a variable rail you can point at one subsystem at a time, the Fabric and the peripherals among them. It streams real-time energy as comma-separated values, and switches and jumpers let you isolate subsystems for measurement accuracy. The free Energy Profiler on Efficient Labs reports energy for named regions of your code.

The kit ships with an evaluation board, a USB-A to USB-C cable, pre-loaded demo firmware, quick-start documentation and software development kit access. It has 72 general-purpose input-output pins, is Arduino UNO and MKR shield compatible for digital functions, runs from 1.8 V to 5.5 V, and takes power from USB, a JST battery connector, an external supply or Arduino VIN, with a USB programmer and JTAG on board. There is also a Cloud Evaluation Kit if you would rather not wait for hardware.

Silicon you can reach without waiting for a board. You compile your own code and run it on an Electron E1 remotely, so you can put a real workload on the part today rather than after a shipment clears. Teams typically start there and move to the physical kit when they need to drive their own sensors or measure energy on their own board.

Yes. The Lifetime Modeler on Efficient Labs is free and needs no login. It takes your duty cycle and battery capacity and models device lifetime from measured kernel energy. Treat the result as a model built on measured energy, not as a measured battery life.

Over USB. The board carries a USB-based programmer and JTAG, so you flash from your host and debug in place. Compile with `-g` for source-level debug information and you get breakpoints, watchpoints and variable inspection from a standard debugger. Pre-loaded demo firmware runs out of the box, so you can confirm the board is alive before your own code is ready.

Free browser tools on Efficient Labs, the Board Viewer, Pin Mapper, EVK Getting Started Guide, Energy Profiler and Lifetime Modeler, need no login either.
