5V Boostybaby Ultra Small High Power Voltage Booster

Radically extend your flight time and improve your video reliability on 1S builds with this 5V voltage booster

One of the major challenges with digital or longer-range 1S builds is supplying enough power to the video transmitter, along the whole discharge curve of the battery.

In most cases, Li-po batteries can be discharged down to 3.5 or even 3.3v.

That is already edging the limit of the HDZero Whoop Lite VTX (which tends to completely brownout below 2.8V and will not restart unless power-cycled)

But even more so on Li-ion builds whose batteries can be discharged down to 2.5v – All while showing higher voltage sag under load, which can turn off your video under the slightest punchout past mid-battery capacity

Fractal Engineering selected the best-suited power IC for their specific 1S need and found this outstanding chip, boasting impressive specs that fit exactly the use case.

They then designed the circuit around it from the most reputable component manufacturers, and out came this remarkably capable piece of gear that can definitely be trusted to supply consistent, reliable power all the way through 1S batteries.

Successor of the Boostyboi, the Boostybaby retains all of the performance in a now much smaller footprint, less than half the size and weight, at not even 0.4g! This makes it a viable option to add reliable video to any 1S digital or high power video build, from nano long range to tiny whoops. 

It also retains the remote disable pad added in the BB Rev-02, allowing you to switch off the output from the FC when pulled to ground. That will allow you to turn off the connected VTX remotely, from your radio, whether be it to save battery, cool it down or simply reboot it in the event it got wonky. To use it, I suggest remapping vtx power resource in Quicksilver to your Buzzer pad, and wire it to the /EN pad.
