Introduction

BLHeli_32, a popular firmware for electronic speed controllers (ESCs) used in drones, has been a staple in the community for its performance, flexibility, and ease of use. However, rumors and discussions have surfaced recently, suggesting that BLHeli_32 might be “dead.” This article explores the current state of BLHeli_32, its development status, and what the future might hold for ESC firmware.

The Rise of BLHeli_32

BLHeli_32 was introduced as an upgrade to the BLHeli_S firmware, offering several advantages:

• 32-bit Microcontroller: The switch to a 32-bit microcontroller allowed for more precise control and smoother operation.
• Increased Features: BLHeli_32 brought in advanced features like telemetry, bidirectional DSHOT, and improved motor timing options.
• Enhanced Performance: With better hardware support, BLHeli_32 provided faster response times and better efficiency.

These improvements made BLHeli_32 a favorite among hobbyists and professional drone racers alike.

Current Development Status

As of 2024, there have been concerns regarding the active development and support of BLHeli_32. Key points to consider include:

• Lack of Recent Updates: The firmware has not seen significant updates or new features in recent times, leading to speculation about its ongoing development.
• Community Feedback: Users have reported issues with the lack of response from developers and slower integration of new hardware support.
• Competition: Other ESC firmware options, such as AM32 and KISS, have gained popularity, offering robust features and active development communities.

Alternatives to BLHeli_32

With the potential decline in BLHeli_32’s development, several alternatives have emerged, each with its own set of features and advantages:

• AM32: An open-source ESC firmware that supports 32-bit microcontrollers and offers a range of advanced features. Its active development community ensures regular updates and improvements.
• KISS ESC: Known for its simplicity and performance, KISS ESC firmware provides a reliable alternative with a focus on ease of use and high performance.
• BetaFlight ESC Firmware: While primarily a flight controller firmware, BetaFlight’s integration with ESCs has improved, providing a cohesive ecosystem for drone enthusiasts.

The Future of ESC Firmware

The future of ESC firmware is likely to see continued innovation and diversification. Key trends to watch include:

• Open Source Development: Projects like AM32 demonstrate the power of community-driven development, which may lead to more open-source alternatives gaining traction.
• Integration with Flight Controllers: Closer integration between ESC firmware and flight controller firmware can lead to more streamlined setups and improved performance.
• Focus on Performance and Efficiency: As drone technology advances, there will be a continued push for more efficient and high-performance ESC firmware to meet the demands of modern drones.

Conclusion

While BLHeli_32 has been a significant player in the ESC firmware market, its future seems uncertain due to a lack of recent updates and growing competition. However, the landscape of ESC firmware is evolving, with new alternatives and ongoing innovations shaping the future. Drone enthusiasts should stay informed about the latest developments and be open to exploring new firmware options to keep their setups at the cutting edge.
