Power your Raspberry Pi from a LiPo or Li-Ion battery with this ultra-compact power supply. The 0.8mm thick PCB can be soldered directly to the GPIO header or attached via the included female header for a removable solution. Uses the TPS61232 step-up boost converter for up to 96% efficiency. Features automatic shutdown at 3.0V to protect your battery and a low battery warning signal on GPIO 4. Key Features Ultra-Compact – 0.8mm thick PCB, sits low on the Pi High Efficiency – Up to 96% with TPS61232 converter 1.5A Output – Continuous current for Pi operation Battery Protection – Auto shutdown at 3.0V Low Battery Warning – GPIO 4 asserts high at 3.4V Ultra Low Standby – 15µA quiescent current JST Connector – Standard 2-pole for LiPo/Li-Ion batteries Specifications Converter: TPS61232 Step-Up Boost Output Current: Up to 1.5A continuous Low Battery Warning: 3.4V (GPIO 4) Shutdown Voltage: 3.0V Standby Current: 15µA PCB Thickness: 0.8mm Compatibility: Pi Zero, A+, B+, 2, 3 Package Contents 1× LiPo SHIM 1× 2×6 Female Header 1× Rubber Foot Note: This is a power supply only, not a charger. You'll need a separate LiPo charger to recharge your batteries.
