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!
Due to the voltage drop caused by the Raspberry Pi, it is recommended to input a minimum of 6.5V to receive a stable 5V output. Anything lower than 6.5V will result in a low voltage warning on the Pi.
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!
Features
- Designed with an advanced switch mode DC-DC regulator IC.

Double 18650 Li-Ion battery Holder for UPS Pico HV3.0A/B/B+ HATs!
The UPS PIco LP/LF/Li-Ion 18650 Battery Holder is an add-on board for the UPS PIco HV3.0A/B/B+ HATs that enables use of the widely available 18650 Li-Ion batteries. Simply swap out the LiPo battery included with the PIco, and you can use 18650's instead! 18650 batteries have a capacity of ~ 3000mAh.
Each 18650 Battery Holder is equipped with inverse battery insertion protection, however we strongly recommend that you use PCB protected batteries.
This is the "Double" 18650 holder, which is able to take two batteries. Batteries are NOT included in the purchase!
The 18650 holder connects to the PIco via a 2-wire JST-XHP-2 Battery Connector, and comes complete with mounting spacers, screws & nuts to mount the PCB above the UPS PIco.
This product is NOT compatible with the Terminal Block PCB.
This product is an add-on board for the UPS PIco and requires a UPS PIco for use. We do not endorsed compatibility with any other product or system, and users who do choose to use the battery holder with another device do so at their own risk.
Please note: Cable colour may vary. Pic is for illustration purposes only.
Pi Supply Switch Features:
- Pi Supply Switch printed circuit board (PCB) v1.1
- All through hole components for assembly
- Flat USB noodle cable
- Two free Pi Supply stickers
- Comes as a kit - easy assembly with some basic soldering
How does it work?
Once you have finished using your Raspberry Pi, you just shutdown using the sudo halt command, and then a couple of minutes after the full and safe shutdown the Pi Supply Switch cuts the power to the computer. From this point, once again, all you would need to do to restore power to the Pi is touch the on button.
There is also a hard power off button for use in emergencies which immediately cuts the power to your Raspberry Pi. Remember to only use this button when absolutely necessary (e.g. Pi has been frozen for a long time) as it risks corruption of the files on your SD card if done at the wrong moment.
What makes the Pi Supply Switch superior to other makeshift solutions available is that it allows you to restart the Raspberry Pi using the sudo reboot command without the power turning itself off. Perfect!
Putting it together
We have made the Pi Supply Switch a self-solder kit which is quick and simple to put together ? even for an absolute beginner to electronics. This means as well as being a nifty little bit of kit to manage your Pi?s power, it is also a great intro to electronics and soldering. As you can see from the pictures the input and output of the switch is fed by a standard USB connection. We even provide you with the USB cable. Once soldered together, is essentially ?plug-and-play? with your existing ?wall wart? power supply unit. We have even packaged the circuit into a small profile so that it fits neatly into your workstation. The Pi Supply Switch is an essential piece of kit for all Raspberry Pi users!Resources
