Compact builds: Perfect for drones

One is for the antenna cable

Can I use this with Arduino

That makes it a practical step up when you want more power than an Arduino-class AVR board without moving to a much larger board

Useful add-ons include hose fittings

DC DC 5A Constant Current LED Driver Module liquid level switch Compact builds: Perfect for dronesBecause these boards have both constant current and constant voltage modes, you can use them to directly drive power LEDs, as they will limit the current through the LED. This board can be used as a: Constant current LED driver Adjustable power supply module with ability to cut off if exceeds preset current limit Battery charger SPECIFICATIONS: Input voltage: 4~38V Output voltage: 1. 25~36V continuously adjustable Output current: adjustable, 5A Output
