The Adafruit Feather Bluefruit Sense takes the popular Feather nRF52840 Express and adds a comprehensive set of sensors, making it an excellent wireless sensor platform with Bluetooth Low Energy, native USB support, and Arduino/CircuitPython compatibility. It features environmental and motion sensing capabilities including 9-DoF motion sensors, proximity/light/color/gesture sensor, PDM microphone, humidity sensor, and barometric pressure sensor.
bitchat is a decentralized, peer-to-peer messaging application that operates over Bluetooth Low Energy (BLE) mesh networks. It provides ephemeral, encrypted communication without relying on internet infrastructure, making it resilient to network outages and censorship. This whitepaper details the technical architecture, protocols, and privacy mechanisms that enable secure, decentralized communication.
