Introduction BLHeli_32 has long been a beloved 32-bit ESC (Electronic Speed Controller) firmware in the FPV (First Person View) drone community. Known for its high performance and reliability, it became an essential tool for drone pilots worldwide. However, in June 2024, BLHeli AS, the Norway-based company behind BLHeli_32, abruptly announced the cessation of its operations, halting all firmware updates and support. BLHeli AS, a small tech firm specializing in drone-related software, left the FPV community in shock with this decision. For longtime users like myself, it was a deeply frustrating blow. In this post, I’ll explore the origins and evolution of BLHeli_32, dive into the reasons for its sudden discontinuation, and discuss its impact and what lies ahead for the FPV world. The History of BLHeli_32 The story of BLHeli_32 begins with BLHeli, an open-source project launched in the early 2010s by German developer Steffen Skaug (aka "sskaug"). Designed for ESCs running 8-bit...
