It integrates a boost converter, battery charger, and protection circuitry on a single compact board. Plug in a standard 18650 cell, and it powers your microcontroller projects without a bulky wall adapter.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e3.7V (single 18650 cell)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaximum Output Current\u003c\/td\u003e\n\u003ctd\u003e1A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCharging Current\u003c\/td\u003e\n\u003ctd\u003e1A (via micro USB)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBattery Protection\u003c\/td\u003e\n\u003ctd\u003eOvercharge, over-discharge, short circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e70mm × 30mm × 15mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003ePortable weather station using ESP8266 and sensors\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eBattery-powered Arduino robot or car\u003c\/li\u003e\n  \u003cli\u003eHandheld gaming console with Raspberry Pi Zero\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-soil-sensor-data-logger\"\u003eMobile sensor data logger for field use\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis module plugs directly into the VIN and GND pins of most Arduino boards (Uno, Nano, Mega). It also powers ESP8266 NodeMCU and ESP32 development boards via the 5V pin. For Raspberry Pi, connection is made to the 5V and GND GPIO header pins—note that higher current models may require a module with a greater output rating.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eInsert a standard 18650 cell into the holder, ensuring correct polarity. Connect the module’s VOUT pin to the 5V input of your board, and GND to ground. The micro USB port charges the battery; a red LED indicates charging, and a blue LED indicates full charge. The output remains active while charging, so your project can run uninterrupted.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Nano?\u003c\/summary\u003e\u003cp\u003eYes. Connect the module’s 5V output to the Nano’s 5V pin. It works well for low-power projects drawing under 1A.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes this module charge the battery while supplying power?\u003c\/summary\u003e\u003cp\u003eYes. The onboard TP4056 charger powers the boost converter directly while charging the cell, so your project can run from USB power and keep the battery topped up.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use a protected 18650 battery?\u003c\/summary\u003e\u003cp\u003eA protected cell is longer than a standard 18650 and may not fit the holder. Use an unprotected flat-top 18650 for best fit and performance.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
