The Arduino Nicla Voice packs machine-learning capabilities on the edge into a tiny fingerprint. Implement always-on speech recognition with the Nicla Voice. The board integrates a dedicated Neural Decision Processor Syntiant NDP 120 able to run multiple AI algorithms at the same time. Leverage the built-in microphone, nRF52832 microcontroller, Bluetooth Low Energy module, 6-axis IMU and 3-axis magnetometer to create your own wireless sensor network for machine learning applications with low power consumption capabilities.

Seeed Studio XIAO nRF52840 Sense Plus, powered by Nordic chipset with FPU, brings more SMD pins to this tiny Bluetooth senor dev board. While maintaining all the capabilities of the standard version including onboard IMU and PDM microphone, Bluetooth 5.0, NFC, and low power consumption, this Plus variant features redesigned castellations and pad layout on the back, offering 9 additional GPIOs specifically for advanced Bluetooth projects requiring expanded I/Os via SMD board-to-board soldering. With native TensorFlow Lite, it's your ideal development platform for advanced embedded Machine Learning and AIoT projects.
