Nodemcu32s module Allinone wireless MCU based on the ESP32 core that provides WiFi, Bluetooth (classic) and Bluetooth Low Energy (BLE) in a single module. Wide connectivity options: WiFi: supports a broad range of network connections and can access the Internet directly through routers. Bluetooth: enables pairing with mobile phones and can broadcast BLE beacons for signal detection. Flexible performance and realtime capability: Clock frequency is adjustable from 80 MHz to 240 MHz to balance performance and power usage. Supports RTOS for realtime task management. Generalpurpose and versatile: Generalpurpose WiFi+BT+BLE MCU module suitable for a variety of projects. The ESP32 core is scalable and selfadaptive, supporting different project scales and requirements. Compatibility and integration: Combines traditional Bluetooth, BLE and WiFi in one module, facilitating communication with mobile devices and BLE beaconbased systems. Use scenarios Smart home and IoT gateways: Connect sensors and devices over WiFi or Bluetooth, manage devices via mobile apps, and optionally broadcast or detect BLE beacons for presence and proximity sensing. BLE beacon and asset tracking: Deploy BLE beacons for location or proximity detection and relay data through WiFi to cloud services or local servers. Edge IoT applications: Run realtime data collection and processing tasks with RTOS, interfacing with smartphones, routers, and BLE devices for robust edge computing.
