Compact PCB module for flight controllers, available as an LED parameter adjustment module or a USB powered power module. The LED version provides clear light indication for fast parameter tuning. The power version uses a USB power supply design to deliver stable and efficient power. Small, reliable, and broadly compatible with full series flight controllers. Key benefits Fast parameter setup: LED indication makes it easier to view and change flight controller parameters without complex tools. Stable USB power: USB power design supplies consistent and efficient voltage for reliable operation. Wide compatibility: Designed to work with a full series of flight controllers, reducing compatibility concerns during installation. Space saving and lightweight: Compact PCB size fits tight installations and keeps added weight to a minimum. Reliable performance: Carefully designed PCB ensures consistent matching with flight controllers and steady operation.
