Today we’re diving into two awesome new Meshtastic devices sent over by Elecrow the ThinkNode M1 and ThinkNode M2. These portable LoRa-powered nodes are designed for decentralized, off-grid communication using the Meshtastic protocol. In this unboxing and first-look video, I cover: The key specs and differences between the M1 and M2 Built-in GPS, antennas, and screen controls How to connect each device to the Meshtastic app A quick test using my T-Deck to confirm message delivery Practical thoughts on build quality, usability, and features The M1 packs GPS and a larger battery, while the M2 is compact and backpack-ready — both great additions to my growing mesh network. Stay tuned for more Meshtastic content coming soon!

LoRaWAN communication with the Elecrow LR1262 Dev. Board (RP2040) and the Elecrow basic single-channel gateway

I started providing LoRaWAN coverage in my city by mounting the ThinkNode G1 gateway to my attic and I made a portable device to test out the reach that it has.

This project briefly describes how to digitalize analog water meters/other devices with display output only by utilizing Ai-On-The-Edge-Cam devboard. The board takes a picture of the old display, does image recognition and provides output to MQTT server via Wifi, Ethernet or via LoraWan(The Things Network).

The Elecrow M1 Meshtastic device has caught my attention with its unique e-paper display and solid feature set. As someone passionate about IoT, GPS tracking, and mesh network devices, I’ve put this compact node through its paces to see how it performs in real-world scenarios. In this review, I’ll walk you through the ThinkNode M1’s standout features, usability, firmware updates, and how it integrates with the Meshtastic ecosystem. Whether you’re considering this device for your next project or just curious about its capabilities, this deep dive will give you a clear picture of what to expect.

Autonomous LoRaWAN node easily connectible via TTN/Helium networks, supporting downlinks. LaRaWAN node based on Seeed Studio' Wia-E5 module (based STM32WLE), so no additional transceiver needed - the main MCU and LoRa PHY already inside - suitable air quality monitoring, garden, intelligent home, automatization... You may connect load remotely by downlinks - via AO3400A transistor (on board). Optimized for Sensirion SEN54 sensor. MPPT and Li-Ion battery charger for power from 5V++ cheap solar panels. 10+ years of autonomic work with cheap 2W solar panel and standard 1850 Li-Ion battery expected. Sleeping current below 1 mA.

H2S-Dev board is a ready-to-use, Open source hardware, Arduino compatible, LoRaWAN Helium network sensor development board. It is capable of implementing a number of sensor (Basic and Full variant) and positioning applications (Full variant only). The board is mainly targeted to makers and hobbyists.

A research project on developing a full-fledged drive-through kiosk and food delivery system, utilizing LLMs to generate user-specific menus/deals.
