It is designed for projects that need a stable 5V supply from a single-cell LiPo battery, eliminating the need for a separate voltage regulator.\n\nConnect a 500 mAh or larger LiPo battery to the JST PH 2-pin port, charge via USB-C or DC/solar input, and power your 5V project directly from the regulated output. Smart power path management prioritises external power, sending excess current to the battery instead of constantly cycling it.\n\nKey Features\n\n\nUSB Type-C Input – 5V at up to 1A with 5.1k CC resistors for universal compatibility; data lines broken out on the bottom\n\nDC/Solar Input – 5–18V via side pads with near-MPPT solar optimisation\n\nAdjustable Charge Rate – Defaults to 1A, adjustable to 500 mA via jumper\n\nSmart Power Path – Prioritises external power, extends battery life by avoiding charge cycling\n\n5V Regulated Output – TPS61023 boost converter delivering stable 5V at up to 1A\n\nEnable Pad – Disable the 5V boost converter when not needed\n\nMounting Holes – For easy installation in enclosures\n\n\nStatus LEDs\n\n\nOrange – Charging\n\nRed – Fault\n\nGreen – Output active\n\n\nAlso Available\n\n\nbq25185 with 3.3V Buck Board – Same charger with 3.3V regulated output instead\n\nbq25185 Charger (no regulator) – Base charger board without integrated voltage regulation\n\n\n\nTip: For solar-powered projects, use a 5–7V solar panel. Higher voltage panels will only generate excess heat. Connect via the DC input side pads.\n\n\nIdeal For\n\nPortable 5V battery-powered projects\nSolar-powered IoT devices\nProjects requiring USB + solar charging flexibility\nPowering 5V microcontrollers and sensors from a LiPo battery\n\n\n\nNote: Use a 500 mAh or larger LiPo battery for best results. Battery not included.\n\n\nPackage Contents\n\n1× Adafruit bq25185 USB/DC/Solar Charger with 5V Boost Board\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":674,"title":"Default Title","sku":"AF-6106","mpn":"ADA6106","price":17.58,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
