{"title":"SparkFun LiPo Charger/Booster - 5V/1A","handle":"sparkfun-lipo-charger-booster-5v-1a","url":"/products/sparkfun-lipo-charger-booster-5v-1a","description":"The SparkFun LiPo Charger/Booster is a compact board that charges a single-cell lithium polymer battery and boosts its output to a regulated 5V at up to 1A. Built around the MCP73831 charge controller and PAM2401 boost converter, it's an economical solution for powering 5V projects from a LiPo cell.\n\nMultiple connection types are provided for the battery, charge source, and power switch, giving you flexibility in your design. Protection diodes allow you to run multiple cells in series for higher voltage, and boards can be daisy-chained together for increased output. Two status LEDs provide feedback on charging and system state.\n\nKey Features\n\n\n5V / 1A Regulated Output – Boost converter delivers stable 5V from a single LiPo cell\n\nBuilt-In LiPo Charging – MCP73831 charge controller with USB or external power input\n\nFlexible Connections – Multiple connection options for battery, charge source, and switch\n\nDaisy-Chainable – Link multiple boards together for higher output\n\nSeries Cell Support – Protection diodes for running multiple cells in series\n\nStatus LEDs – Two LEDs indicate charge and system status\n\n\nSpecifications\n\n\nOutput Voltage – 5V (regulated)\n\nOutput Current – Up to 1A\n\nCharge Controller IC – MCP73831\n\nBoost Controller IC – PAM2401\n\nInput – USB or external charge source\n\n\n\nWarning: This board does not have undervoltage or other battery protection features.
