QuickFeather Combines Low-Power MCU with Embedded FPGA in a Feather Form Factor

QuickLogic's open source board targets machine learning applications with an Arm Cortex-M4F and FPGA EOS S3 SoC, plus sensors.

QuickLogic has launched a completely open source, Feather-compatible implementation of their EOS S3 SoC on Crowd Supply, bringing a combined Arm Cortex-M4F and FPGA package to the popular form factor. In addition to the Arm and soft cores of the EOS S3, the QuickFeather is equipped with an on-board microphone, accelerometer, pressure sensor, and LiPo connector/charger.

QuickLogic took great care to ensure that the QuickFeather is open source all the way down — even using open source PCB design software KiCad to lay out the board (full source available on GitHub). QuickFeather supports the Zephyr RTOS via their own fork, and FreeRTOS via their QORC SDK. Simulation and continuous integration is available via Antmicro's Renode framework. With its M4F and eFPGA, QuickLogic is targeting embedded machine learning applications, boasting TensorFlow Lite and SensiML Analytics Toolkit support.

A look at its key features:

  • QuickLogic EOS S3 Processing Platform
  • 80MHz Arm Cortex-M4F microcontroller
  • Embedded FPGA with 2400 effective logic cells
  • mCube MC3635 accelerometer
  • Infineon DPS310 pressure sensor
  • Infineon IM69D130 MEMS microphone
  • GigaDevice GD25Q16CEIGR 16Mbit on-board flash memory
  • SWD programming connector
  • USB or a single Li-Po battery power via standard JST connector
  • Integrated Microchip MCP73831/2 battery charger
  • USB data signals tied to eFPGA programmable logic
  • UART via I/O headers
  • I²C, I²S, SPI
  • User and reset buttons
  • RGB LED
  • Compatible with Feather form factor and standard 0.1" breadboards

QuickLogic's campaign is now live on Crowd Supply, priced at $59 for a single board — or you can simulate one right now on Renode!
