Lua based interactive firmware for ESP8266, ESP8285 and ESP32

The official firmware for Meshtastic, an open-source, off-grid mesh communication system.

📟 JSON library for Arduino and embedded C++. Simple and efficient.

Open-source telemetry dashboard. Supports UART, BLE, MQTT, Modbus, CAN Bus and more.

A low-power E-Paper weather display powered by an ESP32 microcontroller. Utilizes the OpenWeatherMap API.

The ESP32-BlueJammer (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer) disrupts 2.4GHz communications. Using an ESP32 and nRF24 modules, it generates noise and unnecessary packets, causing interference between the devices communicating, making them unable to work as intended. Ideal for controlled disruption and security testing.
