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. 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).
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 LiPo SHIM as "a slick bit of kit" and "a great option for providing safe power for a portable project" in their four star review.

Features
0.8mm thick PCB
Shaped to sit as low as possible on the Raspberry Pi
2-pole JST connector ideal for most LiPo/LiIon batteries
Power and low battery LED indicators
Supplies up to 1.5A continuous current (15uA quiescent current)
Low battery warning at 3.4V (asserts GPIO #4 low)
Automatic shutdown at 3.0V to protect your battery
VBAT+, GND, and EN pins available to break out
2x6 0.1"female header (optional, for non permanent installation)
Includes rubber foot to space LiPo SHIM away from your Raspberry Pi
Compatible with Raspberry Pi 3, 2, B+, A+, Zero, and Zero W
Requires soldering
Software
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.
Our software does not support Raspbian Wheezy.

小小的LiPo / LiIon電源適用於所有版本的Raspberry Pi!
我們熱愛手機項目,但擁有獨立,光滑,整潔的電源解決方案總是很棘手。 LiPo SHIM(前身為Zero LiPo)旨在為您提供最緊湊的Raspberry Pi電源。
您可以將0.8毫米厚的PCB直接焊接到您的Pi上的GPIO引腳上以獲得永久性解決方案,或者在提供的2x6 0.1“母頭上焊接,這將允許您隨時移除零LiPo(但會阻塞GPIO引腳)。
我們使用德州儀器的TPS61232升壓轉換器,效率高達96%。電路板包括電源開啟和電池低電量指示燈LED。在關機期間(由於欠壓或外部選擇),靜態電流僅為15uA sip。
MagPi將LiPo SHIM描述為“一套漂亮的工具包”和“為便攜式項目提供安全電源的絕佳選擇”。
