QuickFeather Development Kit

Supported by 100% Open Source Hardware
The QuickFeather Development Kit is a small form factor system ideal for enabling the next generation of low-power
Machine Learning (ML) capable IoT devices. Unlike other development kits which are based on proprietary hardware
and software tools, QuickFeather is based on open source hardware, compatible with the Adafruit Feather form
factor, and is built around 100% open source software (including the Symbiflow FPGA Tools, Zephyr and FreeRTOS
Real Time Operating Systems, and Renode).
The QuickFeather is powered by QuickLogic’s EOS™ S3, the first eFPGA-enabled Arm Cortex® M4F MCU.
Other functionality includes:• GigaDevice 16-Mbit of flash memory GD25Q16CEIGR• mCube MC3635 accelerometer• Infineon DPS310 pressure sensor• Infineon IM69D130 PDM digital microphone• Powered from USB or a single Li-Po battery• Integrated battery charger• USB data signals tied to programmable logic• Powered from USB or a single Li-Po battery• Integrated battery charger• USB data signals tied to programmable logic

EOS S3 Benefits• No more multi-gigabyte software installs, no more of the hassles associated with proprietary tools,
no more vendor-specific hardware incompatible with the industry• QuickFeather is small, Feather compatible, inexpensive, and is 100% supported by open source tools• With a Cortex M4F MCU and integrated eFPGA, the onboard EOS S3 lets you innovate with 100% open
source hardware and software
