Pre-soldered male header pins make it plug‐and‐play on a breadboard, while full Arduino IDE compatibility ensures you can start programming immediately. It’s a reliable, ready‐to‐use platform for embedded projects, sensor logging, and rapid prototyping.\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\u003eMicrocontroller\u003c\/td\u003e\n\u003ctd\u003eATmega328P\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDigital I\/O Pins\u003c\/td\u003e\n\u003ctd\u003e14 (6 provide PWM output)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAnalog Input Pins\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eClock Speed\u003c\/td\u003e\n\u003ctd\u003e16 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlash Memory\u003c\/td\u003e\n\u003ctd\u003e32 KB (2 KB used by bootloader)\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\"\u003eA weather station that logs temperature, humidity, and pressure onto an SD card\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-line-following-robot\"\u003eA line-following robot using IR sensors and motor drivers\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-automatic-plant-watering-system\"\u003eAn automatic plant watering system with a soil moisture sensor and pump\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eA simple game controller or MIDI device over USB\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis board works directly with the Arduino IDE – just select “Arduino Nano” from the board menu. It shares the same pinout and form factor as the original Arduino Nano, so most shields and breadboard layouts are compatible. Power it via the Type-C port (5 V) or through the VIN pin (7–12 V). The on-board LDO regulator supplies a steady 5 V rail. I\/O pins operate at 5 V; use level shifters when interfacing with 3.3 V sensors or modules.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eThe pre-soldered dual-row headers slot directly into any standard breadboard. The CH340G chip requires a driver – newer operating systems often install it automatically; otherwise download it from the manufacturer’s site. VIN and GND pins are clearly marked; do not exceed 12 V on VIN. Each I\/O pin can source up to 40 mA, but the total current draw should stay below 200 mA to avoid overheating the regulator.\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 the Arduino IDE?\u003c\/summary\u003e\u003cp\u003eYes. After installing the CH340 driver, open the Arduino IDE, select “Tools → Board → Arduino Nano”, choose the correct processor (ATmega328P) and port, and upload. The board comes with the Arduino bootloader pre-loaded.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat driver does the CH340 need?\u003c\/summary\u003e\u003cp\u003eThe CH340G USB-to-serial chip requires a driver. Windows 10\/11 usually fetch it automatically via Windows Update. For older OS versions, or if not recognised, download the driver from the WCH website. macOS and Linux often have native support, but a signed driver may be needed on recent macOS releases.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the Type-C connector carry data or just power?\u003c\/summary\u003e\u003cp\u003eThe USB Type-C port fully supports data transfer and power. The CH340G chip handles serial communication, so you can upload sketches and use serial monitor just like with a micro USB board.\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.
