LiPo SHIM – Power Supply for Raspberry Pi
If you want to keep the end result of your project neat and compact, LiPo SHIM will provide you with the slimmest Raspberry Pi power supply there is.
You have the option either to solder the 0.8 mm thick PCB directly onto the GPIO pins on your Raspberry Pi for a permanent solution, or, if you want a temporary solution, to solder on the provided 2×6 0.1" female header which will allow you to remove LiPo SHIM at any time (but will block the GPIO pins).
The PCB features 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 15 µA.
- 0.8 mm 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 1.5 A continuous current (15 µA quiescent current)
- Low battery warning at 3.4 V (asserts GPIO #4 low)
- Automatic shutdown at 3.0 V to protect your battery
- VBAT+, GND, and EN pins available to break out
- 2×6 0.1" female header (optional, for non permanent installation)
- Includes rubber foot to space LiPo SHIM away from your Raspberry Pi
- LiPo SHIM pinout
- Compatible with all 40-pin header Raspberry Pi models
- Requires soldering
- Battery not included
In the GitHub repository you'll find a one-line installer that will initiate a clean shutdown when the low battery warning is triggered and GPIO #4 is pulled low.
The VBAT+ and GND pins that are broken out can be used as alternative way to inject power, for instance, if you wanted to solder on your own JST connector with wires to make it stretch a bit further.
The EN pin can be pulled to ground to cut the power output from LiPo SHIM.
