Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR0579:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Solar Power Manager Micro is a micro power, high-efficiency [solar power](https://core-electronics.com.au/power-batteries/solar-power.html) management module, designed for powering IoT based low-power [wireless](https://core-electronics.com.au/wireless.html) sensors or controllers with 1V~3V small size [solar panels](https://core-electronics.com.au/power-batteries/solar-power/panels.html). Benefited from its extremely low power dissipation and MPPT (maximum power point tracking), the module is able to maximize the conversion efficiency of solar energy under weak sunlight. These features make low-power wireless devices charge-free and battery replacement-free possible by pure solar power. The module employs constant voltage ratio MPPT (Maximum Power Point Tracking) algorithm to maximize output power of the solar panel under various sunlight. It can charge a 3.7V lipo battery through solar or USB, providing charge current up to 70mA or 100mA respectively. A 3.3V 90mA regulated output can handle burst current of most low-power wireless devices during transmitting or receiving. In low-power solar projects, lipo battery may suffer from over-discharge problem when it is cloudy for days, or the capacity of battery can not meet the device’s need. The battery over-charge and over-discharge protections are designed to prevent such problems to extend battery life. ## ****Board Overview**** #### **![DFR0579-Solar Power Manager Micro Board Overview](https://core-electronics.com.au/attachments/localcontent/DFR0579-SolarPowerManagerMicroBoardOverview_719032918fc.jpg)** ### ## **Connection Diagram** ### Power micro:bit with Small Solar Panel ### ![DFR0579-Power micro:bit with Small Solar Panel](https://core-electronics.com.au/attachments/localcontent/DFR0579-PowermicrobitwithSmallSolarPanel_3272212630c.jpg) ### **Power Firebeetle Series with Small Solar Panel** ### **![DFR0579-Power Firebeetle Series with Small Solar Panel](https://core-electronics.com.au/attachments/localcontent/DFR0579-PowerFirebeetleSerieswithSmallSolarPanel_757389d7019.jpg)** ## Features - Constant voltage ratio MPPT algorithm, maximizing solar power conversion - Designed for 1V ~ 3V small solar panels, ultra low power design - Solar/USB two charging methods - Multiple protections extending battery life ## Applications - Wireless Sensor Network - Bluetooth iBeacon - Solar Powered Toys ## Specifications - **Micro Solar Power Management Module** - Solar Power Management IC: SPV1050 - Solar Input Voltage (SOLAR IN): 0.5V~4V - Battery Input (BAT IN): 3.7V Lithium Battery - Maximum Charge Current: 100mA@USB IN;70mA@SOLAR IN - Over-charge Protection Threshold: 4.2V - Over-discharge Protection Threshold: 3.1V - Regulated Power Supply: 3.3V 90mA@BAT IN 3.7V - Quiescent Current: <3 uA - Protection Functions - BAT IN: Over-discharge/Over-charge/Reverse Connection Protections - OUT: Short Circuit/Over Current Protections - Operation Temperature: -40°C ~ 85°C - Dimension: 30.0mm\*30.0mm **Solar Panel 2V 160mA** - Nominal Voltage (VMP): 2V - Nominal Current (IMP): 160mA - Open Circuit Voltage (IOC): 2.4V - Short Circuit Current (ISC): 190mA - Solar Cell Material: Monocrystalline Silicon - Other Features: Waterproof, Oil Resistant and Corrosion Resistant - Dimension: 50mm\*50mm ### Documents - [Product wiki](https://www.dfrobot.com/wiki/index.php/Solar_Power_Manager_Micro_SKU:_DFR0579) - [More Documents](https://www.dfrobot.com/wiki/index.php/Solar_Power_Manager_Micro_SKU:_DFR0579#More_Documents) ### Parts List | Solar Power Manager Micro | x1 | |---|---| | Monocrystalline Silicon Solar Panel 2V 160mA 50\*50mm | x1 | | Red Single Conductor Wire 15cm 24AWG | x2 | | Black Single Conductor Wire 15cm 24AWG | x2 | | PH2.0-2P Male Power Wire 15cm | x1 | | XH2.54-2P Header | x2 | ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/d/f/dfr0579-900x600.jpg)
