Ultra-Small DC-DC 5V 3A BEC Buck Step-Down Module

A tiny DC-DC buck regulator that steps a higher supply down to a steady 5 V at up to 3 A. Use it to power receivers, GPS modules, LEDs and other 5 V electronics from the flight pack when the flight controller or ESC has no spare BEC output.

Key features

• Switching buck design with efficiency up to 96%, so it runs far cooler than a linear regulator
• Built-in over-current and thermal protection
• Ultra-small board that tucks into tight frames and fuselages

Specifications

• Output voltage: 5 V DC
• Output current: 3 A max
• Efficiency: up to 96%
• Protection: over-current, thermal

Add up the current of everything on the 5 V rail before wiring it in, as servos and LED strips can pass 3 A on their own. If you plan to feed it straight from a 4S or 6S pack, message us to confirm the input range first, and mount it away from receiver antennas to keep switching noise off the RF link.
