Bluejay ESC Firmware

With BB51 ESC solution, Air Brushless Flight Controller is based on A_X_5_96KHz_V0.19.hex for BB51 Bluejay hardware, it supports D-shot300, D-shot600, and even RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies.

DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.

Connecting External RX/VTX

Please note that UART2 has connected to the VTX by default. This FC reserves 3 complete full-featured serial ports that can be used for external CRSF/SBUS receivers, GPS, HD VTX, or other serial devices. You can refer to the below picture.

Attention

VTX Power: Higher VTX power consumes more energy and generates more heat, reducing flight time. For better flight time in indoor scenarios, use 25~100mW power.
Motor Wiring: Only soldering is supported for motor wiring on the flight control. Avoid terminal plugging.
VTX Antenna: Connect and install the image transmission antenna before powering on the flight control. Alternatively, set transmission power to 0 to avoid burnout.

Features:

Air Brushless Flight Controller, the first 1S FC that utilizes the G473 processor, experienced a remarkable 55% increase in computing speed and lightning-fast response times for precise racing and complex freestyle maneuvers, surpassing the F411.
