SkyGuy Max is an ELRS receiver with a single antenna, suitable especially for long-range drones and aircraft not only with ArduPilot firmware. Thanks to the robust CNC aluminum housing, which serves as a heatsink, and a high telemetry output power of up to 1000mW, it is suitable for drones where mechanical resilience and data feedback (e.g., Mavlink transmission) are priorities. The receiver operates at a frequency of 2.4GHz. It utilizes the ESP32-C3 microprocessor together with the SX1280 RF chip. The receiver weighs 6 grams. The aluminum heatsink also ensures the IPEX1 connector and prevents the antenna from coming loose.
