📖10 KM Range with NO Internet? REYAX RYLR998 LoRa Setup amp; Field Test

In this video, we tested the REYAX RYLR998 LoRa module in real-world conditions using two Arduino Nanos to check its actual range limits! We built both Transmitter and Receiver circuits, powered them using a Type-C Power Bank Booster Module (5V output), and tested data transmission across two different scenarios:

1. Push Button amp; LED Trigger: Pressing a button on the transmitter instantly lights up a red LED on the receiver.

2. Automated LED Blink Code: Sending continuous data packets to monitor signal stability over long distances. For the field test, we kept the receiver inside our office and took the transmitter outside on a long-distance drive.

📖Create Your Own Offline Encrypted Chat with ESP32 & RYLR998

How do we send text without leaving a single trace on servers or web networks?
The secret is at the physical layer: complete decoupling from the internet.
We built a total P2P messaging system using our REYAX RYLR998 and ESP32. No Wi-Fi, full impedance and power control (up to 22 dBm), and maximum secrecy by design.

📖Built an Indoor AirTag (NO GPS Needed!) | REYAX RYUW122 + ESP32

In this video: We built a DIY UWB (Ultra Wide Band) distance measurement and tracking system using the REYAX RYUW122 Lite UWB module, Arduino/ESP32, OLED display, and a real-time web dashboard.

The system can measure the distance between the UWB devices and display the result on an OLED screen. The ESP32 also provides a Wi-Fi web interface where you can monitor the distance, view a real-time graph, configure target distance and tolerance, and check the system status.

📖DIY Long-Range LoRa Transmitter (10Km) with OLED Telemetry: Reyax RYLR993 Guide

The YouTuber MaDDy Regal shows how to build a long-range wireless remote control system using the REYAX RYLR993 Lite LoRa module and Arduino. This project consists of a custom transmitter and receiver that communicate over LoRa. The transmitter features an analog joystick and two push buttons, allowing you to control both PWM and digital outputs wirelessly. The receiver can drive devices such as servo motors, LEDs, relays, DC motors, and many other electronic loads.
