Built around the SPV1050 IC with MPPT (Maximum Power Point Tracking), it maximises solar conversion efficiency even under weak sunlight — enabling charge-free, battery-replacement-free operation for low-power IoT devices.\n\nThe module charges a 3.7 V lithium battery via solar (up to 70 mA) or USB (up to 100 mA), and provides a regulated 3.3 V 90 mA output capable of handling burst current from wireless transmitters. Over-charge, over-discharge, and reverse connection protection extend battery life in long-term deployments. A 2 V 160 mA monocrystalline solar panel is included.\n\nKey Features\n\n\nMPPT Algorithm – Constant voltage ratio tracking for maximum solar efficiency\n\nUltra-Low Quiescent Current – <3 µA standby draw\n\nDual Charging – Solar (up to 70 mA) or USB (up to 100 mA)\n\n3.3 V Regulated Output – 90 mA continuous for low-power wireless devices\n\nBattery Protection – Over-charge, over-discharge, and reverse connection\n\nOutput Protection – Short circuit and over-current\n\nSolar Panel Included – 2 V 160 mA monocrystalline panel\n\n\nModule Specifications\n\n\nManagement IC: SPV1050\n\nTopology: DC-DC Boost\n\nSolar Input (SOLAR IN): 0.5–4 V\n\nBattery: 3.7 V single-cell Li-Po/Li-Ion\n\nMax Charge Current: 70 mA (solar) / 100 mA (USB)\n\nOver-Charge Threshold: 4.2 V\n\nOver-Discharge Threshold: 3.1 V\n\nRegulated Output: 3.3 V, 90 mA\n\nQuiescent Current: <3 µA\n\nOperating Temperature: −40 °C to +85 °C\n\nBoard Size: 30 mm × 30 mm\n\n\nSolar Panel Specifications\n\n\nNominal Voltage (Vmp): 2 V\n\nNominal Current (Imp): 160 mA\n\nOpen Circuit Voltage (Voc): 2.4 V\n\nShort Circuit Current (Isc): 190 mA\n\nCell Material: Monocrystalline silicon\n\nProperties: Waterproof, oil resistant, corrosion resistant\n\nPanel Size: 50 mm × 50 mm\n\n\nIdeal For\n\nWireless sensor networks\nBluetooth iBeacon devices\nSolar-powered IoT sensor nodes\nLow-power environmental monitors\n\n\nPackage Contents\n\n1× Solar Power Manager Micro board\n1× Monocrystalline silicon solar panel (2 V, 160 mA, 50 mm × 50 mm)\n2× Red single conductor wire (15 cm, 24 AWG)\n2× Black single conductor wire (15 cm, 24 AWG)\n1× PH2.0 2-pin male power cable (15 cm)\n2× XH2.54 2-pin headers\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":7309,"title":"Default Title","sku":"DF-DFR0579","price":32.92,"on_sale":false,"in_stock":true,"available_quantity":97,"option1":"Default Title"}]}
