Description

NewBeeDrone LionBee 3inch long range ELRS2.4 AIO developer kit

Always verify battery polarity before connecting USB power. Incorrect polarity may cause permanent hardware damage.

When operating the VTX at MAX power levels, please ensure the VTX antenna is securely fastened before powering on. Operating at high output without a properly connected antenna may lead to permanent hardware damage or VTX burnout.

The
NewBeeDrone LionBee Long Range Developer Kit is a completely new approach to 1S long-range FPV drone design. Engineered around an innovative
18650 structural-integrated flight controller, the LionBee introduces breakthroughs that redefine what a micro long-range drone can be. By mounting the AIO FC directly onto the battery chamber, the frame gains natural vibration resistance, reduced complexity, and improved electrical efficiency—something never before seen in the FPV world.

To unlock true 1S long-range performance, LionBee features a
custom 0.5mm brass high-current conduction system, eliminating the bottleneck found in traditional 18650 battery holders. This high cross-section path allows modern high-discharge 18650 cells—such as JP30—to reach their full potential, providing
freestyle-capable thrust on a single cell.

LionBee also introduces the
world’s first 1S ESC built on a 32-bit MCU, developed in collaboration with the AM32 team for optimized performance. At the core of the AIO is the
AT32F435 288MHz processor, delivering exceptional computational power for advanced flight control, video transmission, and integrated receiver functions. Despite the single-sided PCB layout, the system includes an
800mW Smart-Max VTX, providing temperature-adaptive power output for safe and reliable long-range video transmission.

A full
reverse-polarity protection circuit ensures that accidentally inserting the 18650 battery backward will not damage the FC, ESC, PA, or other electronic components—an essential safeguard for field operation. The redesigned
modular replaceable battery chamber features factory-soldered brass terminals and allows quick replacement if damaged during impact. (Please note that the reverse polarity protection circuit does not function while also having USB plugged in)

Released as a
Developer Kit, the LionBee is designed for pilots, engineers, and innovators who want to take part in shaping the next generation of micro long-range FPV. It is more than a product—it’s an expandable, experimental platform for R&D exploration and community-driven evolution.
