Can this be used with the Pi touchscreen?
Other step down converters have a habit of freezing the screen when working with volumio - would the noise on the current affect the touchscreen operation here?

  • I think you might find the noise from the UBEC could interfere with the touch screen.

UBEC Voltage Output
My new UBEC, when set to 5V, is showing 9V on my meter under no load. Is this normal? I don't want to fry my Pi.

Can this be used with large 12v batteries?
I'm wanting to add a Pi to my solar WISP tower, the batteries there are 12v 100ah. My plan would be to connect this to the batteries and then to a Pi, would that work okay?
  • Yes this should work just fine

UBEC's (Universal Battery Eliminator Circuit's) are simply DC to DC step down voltage regulators! This UBEC is perfect for the Raspberry Pi, as it's able to take high voltages (5.5V up to 26V), and outputs a consistent safe voltage of 5V at up to 3A nominal or 5A max! The Hobbywing 5V 3A UBEC is a switch-mode type, which results in it being much more efficient than linear type UBEC's (so your batteries will last longer!)

UBEC's are perfect for applications where you plan to use the Raspberry Pi in a circuit with high voltages such as robots where you'll be driving motors!

Please Note. UBECs have a noisy output, so we do not recommend powering a Raspberry Pi Zero (or other sensitive 5V device) directly from the UBEC.

Please Note. The Hobbywing UBEC can be set to output either 5V or 6V using an onboard jumper select! Please DOUBLE CHECK your output voltage is correct before connecting your microcontroller or circuit! 


  • Designed with an advanced switch mode DC-DC regulator IC.
  • Battery polarity reversal protection.
  • A metal shield covers almost all the electronic components, and a specially made filter is attached to the output wires to significantly reduce the electromagnetic interference.
  • The working status is shown by an indicator (LED), which lights when the output is in normal range.
  • Output Voltage: [email protected] or [email protected] (Changeable with an output-voltage select jumper)
  • Continuous output current: 3 Amps
  • Maximum output current: 5 Amps
  • Input: 5.5V - 26V (2 - 6 cells lithium battery pack or 5 - 18 cells NiMH /NiCd battery)
  • Size: 43mm*17mm*7mm (L*W*H)
  • Weight: 11g
