We love mobile projects but having a discrete, slick, and tidy power supply solution is always tricky. LiPo SHIM (formerly known as 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 2x6 0.1" female header which will allow you to remove your Zero LiPo at any time (but will block the GPIO pins).
