The tiny little LiPo/LiIon power supply shim for all versions of the Raspberry Pi!
We love mobile projects but having a discrete, slick, and tidy power supply solution is always tricky. The Zero LiPo aims to give you the most compact Raspberry Pi power supply possible.
You can either solder the 0.8mm thick PCB directly onto the GPIO pins on your Pi for a permanent solution, or solder on the provided 2x4 0.1" female header which will allow you to remove your Zero LiPo at any time (but will block the GPIO pins).
We use the TPS61232 step-up boost converter from Texas Instruments that offers up to 96% efficiency. The board includes power on and battery low indicator LEDs. During shutdown (due to under-voltage or external selection) the quiescent current is just 15uA sip.
The MagPi described Zero LiPo as "a slick bit of kit" and "a great option for providing safe power for a portable project" in their four star review.
We've put together a one-line installer that will initiate a clean shutdown when the low battery warning is triggered and GPIO #4 is pulled low. More details are available here in the GitHub repository.
