ExpressLRS (ELRS) is a high-performance open source Radio Control link for RC applications. The Express team officially released its version1.0.0 on July 17, 2021, and it can be recognized as the best RC link in terms of low latency and long range. Since the project was innovated in 2019, many developers and pilots all over the world have enthusiastically participated in it, making it a reality. Its release has certainly brought more energy to this hobby.
- Antenna diversity
- Low-cost hardware
- Low packet interval - 2ms (500Hz)
- Long range - optimization of receiver sensitivity
- Low latency, low jitter, phenomenal timing consistency
- Receivers as small as 10mm x 10mm x0.6mm, 0.44g with antenna
