High-Performance LoRa Communication Device The Elecrow ThinkNode M5 is a compact, portable LoRa communication device designed for off-grid messaging, location sharing, and outdoor use. Powered by an ESP32-S3 processor and an SX1262 LoRa chip, it comes pre-installed with Meshtastic firmware and can be configured conveniently via Bluetooth using the official Meshtastic app. The integrated multi-GNSS module supports GPS, GLONASS, BeiDou, and QZSS for reliable positioning and location sharing. Messages and device information are displayed on the energy-efficient 1.54-inch e-paper screen, while the built-in 1,200 mAh rechargeable battery enables extended mobile operation. With its integrated LoRa antenna, compact housing, RTC, and support for both Meshtastic and MeshCore firmware, the ThinkNode M5 is a practical communication solution for hiking, camping, remote locations, and emergency situations where conventional mobile networks are unavailable.

Master digital electronics – the hands-on way! This bundle includes the book Learning Digital Electronics, featuring 20+ practical projects in Logic and Circuit design, as well as a 100-piece kit – so you can start building logic circuits, counters, displays, and more right away. Learning Digital Electronics (Book) This book is a practical guide to digital electronics, covering the essential components of modern digital systems: number systems, logic gates, Boolean algebra, combinational and sequential logic, and more. Through more than 20 structured projects, you’ll design and build digital systems using real-world components such as logic gates, multiplexers, decoders, flip-flops, counters, and shift registers. The projects range from basic LED logic circuits to digital locks, display systems, traffic light controllers, and timing-based designs. Selected projects introduce the use of tools such as CircuitVerse for circuit simulation, while several designs make use of 74HC-series logic devices, commonly used in digital hardware prototyping. Inside, you’ll find: Clear coverage of number systems and binary arithmetic Logic gate fundamentals and universal gate implementations Step-by-step projects using flip-flops, counters, and registers Real-world design with 74HC-series logic chips Techniques for designing combinational and sequential systems This book takes a design-first, application-driven approach to digital electronics—built around working circuits, tested logic, and hands-on experimentation. Learning Digital Electronics (Kit) This kit has been specially developed to complement the book "Learning Digital Electronics". Since all necessary components are included, you can complete every practical project in the book directly.
