UBECs (Universal Battery Elimination Circuits) are efficient switching voltage regulators that convert a high battery voltage into a regulated voltage suitable for running electronics. UBECs are often used in remote control cars and planes.
There are already many posts in this forum about running a Pi using a UBEC. The advantage of using the one that we supply is that we supply it with a micro USB connector which means that it's really easy to connect it to your Pi. To use other UBECs without this connector you'd have to plug it into the power pins on the GPIO header which can fry your Pi if you get it the wrong way round.
Features of the UBEC are
- Output: 5V/3A and 6V/3A switchable
- Ripple: <50mVp-p(@2A/12V)
- Input: 5.5V to 26V
- Size: 51mm x 16.6mm x 8.5mm
- Weight: 11.5g
- 2.54mm female connectors on input lines
- MicroUSB connector for Pi on output lines
We've also upgraded the Raspberry Pi Robot kit we sell to include this UBEC, greatly improving the battery life of the robot.
