Product description: SparkFun QuickLogic Thing Plus - EOS S3 - machine learning module - SparkFun DEV-17273
QuickLogic Thing Plus board created by SparkFun for developing applications using machine learning. The module is based on a powerful EOS S3 chip with ARM Cortex-M4F eFPGA, being fully supported by Zephyr RTOS and FreeRTOS. The board was based on 100% open source, Feather compatible hardware and built around 100% open source software.
The device features a built-in Li-Pol battery connector and battery charging circuit, a Wake-on-sound PDM microphone, and a low-power, three-axis accelerometer, making it ideal for voice and gesture detection. With the ability to transfer data to an FPGA chip, you can use SensiML, TensorFlow or other tools to run embedded machine learning algorithms. The board also includes a Qwiic connector to quickly connect to an ecosystem of more than 150 I2C-compatible boards, such as sensors, RFID readers, displays, keypads and relays.
