A low-power MCU + embedded FPGA in a Feather form factor with on-board sensors

QuickFeather is a development board for the QuickLogic EOS S3, a low-power System-on-Chip (SoC) that has both an Arm® Cortex®-M4F MCU and an embedded FPGA to enable the next generation of low-power embedded Machine Learning (ML).

The board ties into the Adafruit Feather ecosystem of over 60 pre-existing add-on boards, can be powered from and charge Li-Po batteries, and has an on-board microphone, accelerometer, and pressure sensor.

Open Source Everything

As part of our recently announced QuickLogic Open Reconfigurable Computing (QORC) initiative, we took special care to make everything about QuickFeather open source, from the hardware, to the software, to the tools. The FPGA industry is ripe for the sort of change open source has to offer - QuickFeather is our way of welcoming that change!

Open Hardware & Design Tools

Not only is the QuickFeather board itself open hardware, it was designed in the open source EDA platform, KiCad. Full KiCad project source files and final Gerber files can be found in our GitHub repository.

Open Embedded OS

It’s easy to use QuickFeather with Zephyr RTOS via our QuickLogic fork. Similarly, we’ve integrated FreeRTOS into our QORC SDK, which explicitly supports the QuickFeather board and includes sample code for getting started. Also, there is a QuickFeather integration for NuttX.

Open FPGA Tools

We worked directly with key members of the SymbiFlow community to make sure the embedded FPGA (eFPGA) in the EOS S3 SoC used on QuickFeather is fully supported by SymbiFlow’s excellent Verilog-to-bitstream tools. We also partnered with Antmicro to add support for the EOS S3 SoC in the open source Renode simulation and testing framework.

Open Machine Learning

QuickFeather’s combination of sensors, programmable logic, and low-power microcontroller make it a perfect hardware platform for the open source TensorFlow Lite machine learning tools.

SensiML

For rapid development of custom embedded AI algorithms to run on QuickFeather or any other device based on the EOS S3 SoC, we recommend the SensiML Analytics Toolkit.

Features & Specfications

EOS S3 SoC

The QuickFeather board features the QuickLogic EOS S3 System-on-Chip (SoC), which contains a low-power Arm® Cortex®-M4F processor and an embedded FPGA. The EOS S3 SoC is available in a variety of packages, including QFN and BGA. The QFN version is used on the QuickFeather board, however it is being phased out in favor of the BGA version.

In the Press

Electronic Engineering Journal

"Rather than lofting flaming arrows randomly into the rebel alliance surrounding the castle, QuickLogic cleverly decided to open the gates, let them all in, and feed them dinner."

Adafruit Industries

"Unlike other development kits based on proprietary hardware and software tools, QuickFeather is based on 100% open source hardware, compatible with the Adafruit Feather form factor, and is built around 100% open source software."
