SparkFun QuickLogic Thing Plus EOS™ S3 is a small form factor system intended for enabling low-power Machine Learning (ML) devices. The device is powered using QuickLogic’s EOS S3, an eFPGA-enabled Arm© Cortex©-M4F MCU fully supported with Zephyr RTOS and FreeRTOS. The QuickLogic Thing Plus EOS S3 is based on 100% open-source hardware, compatible with the Feather form factor. It is built around 100% open source software (with support for FreeRTOS, Zephyr, nMingen, Docker, and SymbiFlow).
The SparkFun QuickLogic Thing Plus EOS S3 features an onboard LiPo battery connector and charging circuitry, wake-on-sound PDM microphone, and a low-power, three-axis accelerometer. These features make the board ideal for wearable, voice, gesture sensing applications. Sensor data can quickly move into the embedded FPGA utilizing the strong firmware support for the microphone and accelerator. Furthermore, users can use SensiML, TensorFlow Lite, or other tools to train and run embedded machine learning algorithms specific to individual applications.
Additionally, the QuickLogic Thing Plus EOS S3 includes a Qwiic connector to quickly interface with an ecosystem of 150+ I2C-compatible boards such as sensors, RFID readers, displays, keypads, and relays.
