QuickFeather Development Board

../../_images/feather-board.png

Overview

This repository contains open hardware design files for the QuickFeather development board based on the QuickLogic EOS S3 Sensor Processing Platform. The design files were created by Antmicro in cooperation with QuickLogic. The board has been designed to keep compatibility with the Adafruit Feather ecosystem of evaluation boards. This allows the user to explore functionalities of the EOS S3 platform.

Getting Started

The QuickFeather_UserGuide contains instructions for running the pre-installed example program.

Development ecosystem

Simulation

The board is supported in Renode, the open source simulation framework by Antmicro - you can run a virtual copy of this hardware for software development purposes on your PC. A link to the relevant demo script is provided in Renode’s supported boards section.

Basic Usage

Simple

Connect the micro-usb port of the board to the PC, which will both provide power to the board as well as offer a virtual USB-CDC UART port out of the box.

Advanced

For using the board with advanced scenarios, such as loading a custom FPGA image, an additional dedicated USB-UART board (for example based on the PL2303, FT232 etc.) needs to be connected to the QuickFeather UART pins, as shown below:

+--------------------------+         +--------------+
| QF UART RX(IO_45) [J3.3] +-------->+ USB-UART TX  |
|                          |         |              |
|                          |         |              |
| QF UART TX(IO_44) [J3.2] +-------->+ USB-UART RX  |
|                          |         |              |
|                          |         |              |
| QF GND      (GND) [J3.1] +-------->+ USB-UART GND |
+--------------------------+         +--------------+
