Upgraded Boot button for easier use. No soldering required for the USB mini-board. Direct connection to a 4-in-1 ESC for easy quadcopter VTOL setup. Added dual analog camera switching function. Upgraded PCB process to 20Z thick copper plate, enhancing the current meter's continuous overcurrent capability. The compact size makes it suitable for small FPV carriers or modified hand-launched aircraft. Its innovative design offers strong expandability, allowing for Y3 or quadcopter VTOL setups with 12 PWM channels, also accommodating large carriers and VTOL fixed-wing aircraft. High- gyroscopes and barometers significantly improve stability compared to similar flight controllers. The onboard current meter features dual 5VBEC channels, providing robust BEC current output for its size. Additionally, it supports flexible installation layouts with external USB mini-board and TF card mini-board, and is compatible with and INAV firmware. LED light strips can be connected for enhanced flight effects.
