## Description

The PowerBoost 500 Basic is a compact DC/DC boost converter that takes input from 1.8V or higher and outputs a steady 5.2V — perfect for powering portable 5V projects from batteries. The slightly elevated 5.2V output provides headroom for cable resistance and high-current draws, preventing brown-outs while remaining safe for all 5V electronics. Built around the TI TPS61090 boost converter with synchronous conversion, the module delivers excellent efficiency (90%+) and includes a low-battery indicator LED. Each board comes with a loose USB-A jack for optional soldering. Key Features 1.8V+ Input – Works with LiPo, NiMH, alkaline, and other battery types 5.2V Regulated Output – Safe for all 5V devices with headroom for cable losses 90%+ Efficiency – Synchronous conversion for minimal power waste Low Battery Indicator – Red LED lights when input drops below 3.2V Enable Pin – Completely disconnect output by pulling EN to ground USB Charging Resistors – On-board 500 mA charge-rate data resistors Specifications Converter IC: TI TPS61090 Input Voltage: 1.8V+ Output Voltage: 5.2V DC Output Current: 500 mA+ @ 1.8V, 750 mA+ @ 2.4V (2× NiMH), 1000 mA+ @ 3.7V (LiPo) Internal Switch: 2A (~2.5A peak) Switching Frequency: 700 kHz Quiescent Current: 5 mA (enabled), 20 µA (disabled) Ideal For Battery-powered Arduino and Raspberry Pi projects Portable robotics Wearable electronics Field-deployed sensors and data loggers Package Contents 1× PowerBoost 500 Basic PCB (assembled and tested) 1× USB-A Jack (loose, for optional soldering) Resources TPS61090 Datasheet (TI)
