It combines a Solar Power Manager board for 9V/12V/18V panels with a compact 9V 220mA solar panel.The controller integrates constant-voltage MPPT solar harvesting, charging control for a 3.7V lithium battery, and multiple regulated DC outputs on one board. It can accept power from solar input, USB charging or an AC adapter, helping you design autonomous systems for outdoor and remote deployments.Three independently switchable DC-DC outputs provide 5V, 3.3V and selectable 9V/12V rails for microcontrollers, sensors and wireless modules. The kit is supplied with Solar Power Manager x1, Black Jumper x3, M3 nylon pillar x4, M3 stainless steel screw x4, 14mm*14mm Aluminum cooling fin x1, 14mm*14mm Thermal conductive silicone pad x1, Female DC power jack adapter x1, and Solar Panel (9V 220mA) x1.Features:Constant voltage MPPT algorithm, maximising solar panel efficiency7V~30V wide solar panel input voltageVarious charging mode: solar/AC adapter/USB charger (2A max charge current)Three individual ON/OFF controllable regulated power supply for low-power applicationsAll multi-layer ceramic capacitors (MLCC), safe, stable and high-efficiencyVarious protection functionsUSB connector with ESD shellSpecifications:Solar power management IC: LTC3652Solar input voltage (SOLAR IN): 7V~30VBattery input (BAT IN): 3.7V single-cell Li-polymer/Li-ion batteryCharge current(USB/SOLAR IN): 2A MaxCharging cutoff voltage(USB/SOLAR IN): 4.2V±1%MPPT setting voltages: OFF/9V/12V/18VUSB IN voltage: 5VRegulated power supply: OUT1=5V 1.5A; OUT2=3.3V 1A; OUT3=9V/12V 0.5ARegulated power supply efficiency OUT1 (3.7V battery IN): 86%@50%LoadRegulated power supply efficiency OUT2 (3.7V battery IN): 92%@50%LoadRegulated power supply efficiency OUT3 (9V OUT, 3.7V battery IN): 89%@50%LoadUSB charge efficiency: 84%@1ASolar charge efficiency (18V SOLAR IN): 78%@1AMaximum quiescent current: <3 mABAT IN: over charge /over-discharge /over current /reverse connection protectionOUT1-OUT3/USB OUT: short circuit/over current/overheat protectionSOLAR IN: reverse connection protectionOperation temperature: -40℃～85℃Dimension: 78.0mm*68.0mmSuitable applications include smart solar environment monitoring systems, solar-powered robots, small solar street lamps and portable solar power banks. **Product Type:** Solar Power Manager ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDrMACSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--7982bc035ab15f4c865993bcae4841e65612025f/DFR0535-1.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDrcACSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--319d92cb77393a0ad0e888d3be9f9ec3e4024b2d/DFR0535-family.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDrsACSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--493349571b30e53d955c555b5f64ea84bc644516/DFR0535-detail-001.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDr8ACSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--bffeac5166afc1f7300906dbb24cafec0e1cb73a/DFR0535-detail-002.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDsMACSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--97bf4031ccdd02b98eda4fb48f9c753b3e206224/DFR0535-detail-003.JPG) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
