What is it?

Elecrow ThinkNode-M1 is a high-performance multi-function device integrating advanced wireless communication technology and multiple sensors. It is designed for outdoor adventures, environmental monitoring, and emergency communications. It uses nRF52840 as the main processor and supports Bluetooth. Users can easily configure and monitor it through their mobile phones. M1 comes pre-installed with Meshtastic firmware. Combined with the SX1262 wireless chip, the device can efficiently send and receive LoRa signals, providing users with reliable long-distance communication capabilities. M1 is perfectly compatible with the Meshtastic official App. Users can use the App to configure and manage device parameters, message communication, map and location sharing, network status monitoring, data recording and exporting, custom settings, etc.

The built-in 1.54-inch EPD (Electronic Paper Display) can view data and device status in real-time, which is convenient for users. In addition, M1 has a built-in 1200mAh rechargeable battery with a battery life of more than 48 hours, which meets the needs of long-term outdoor use. The external LoRa antenna supports different frequency selections. The device adopts an integrated closed shell design, which is compact, easy to carry, and durable. The built-in GPS module of M1 can provide accurate positioning in any environment and can be used as an independent communication tool in the absence of network coverage or in emergencies to protect the safety of users.
