Description Stellar ELRS 433MHz
Stellar ELRS 433MHz is a high-performance receiver designed to provide reliable and fast radio communication in remote control and FPV systems. It is based on the open-source ExpressLRS software, which allows users to customize and upgrade the device according to their needs.
Key Specifications:
• Microcontroller: ESP8285.
• RF chip: SX1276, which supports operation in the 150-500 MHz range, including 433 MHz.
• Modulation: LoRa for long range and immunity to interference.
• Update Rate: High data update rate, which provides minimal latency, which is important for FPV racing and long-distance flying.
• Power: Supports DC 4.5 - 16.4V input voltage, making it compatible with various power sources.
• Size and weight: Compact design with a weight of 2.4g, which simplifies integration into various platforms.
The SX1276 is a radio frequency chip from Semtech, known for its high sensitivity down to -148dBm and support for various modulations, including LoRa, FSK, GFSK, MSK, GMSK and OOK. It provides stable and long-distance communication, which is critical for unmanned systems and other Internet of Things (IoT) applications.
By combining the ESP8285 and SX1276, the Stellar ELRS 433MHz receiver offers users a reliable solution for remote control with low latency and long range, which is especially relevant in today's conditions and meets the needs of Ukrainian users.
