Compact and energy-efficient solution combining Bluetooth 5.0 and LoRa (862–930 MHz), ideal for IoT projects requiring long range and low power consumption. It uses the XIAO nRF52840 MCU with Cortex-M4 core and support for multiple interfaces and the LoRa SX1262 module for reliable wireless communication. The kit is perfect for applications such as Meshtastic, asset tracking, sensor networks or educational projects. Seeed Studio 102010710

Versatile ESP32 module with LoRa and Wi-Fi support, designed for monitoring people flow and creating mesh networks in difficult conditions, such as in areas cut off from the network. The device can detect Wi-Fi and Bluetooth signals, allowing estimation of the number of mobile devices in the environment without recording MAC addresses, which protects privacy. The module offers low power consumption, data storage on SD card and data transfer via LoRa WAN or MQTT, making it a reliable and self-sufficient solution for emergency communication. modTTGO LoRa32 v2.1
