It is fully compatible with the Arduino Nano platform and uses the CH340G USB‑to‑serial chip for stable programming and serial communication. This board is perfect for prototyping, robotics, and IoT projects where space is limited and reliability matters.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\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\u003eClock Speed\u003c\/td\u003e\n\u003ctd\u003e16 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital I\/O Pins\u003c\/td\u003e\n\u003ctd\u003e14 (6 PWM capable)\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\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\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eA Bluetooth‑controlled robot using an HC‑05 module and motor driver\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-cold-chain-temperature-data-logger\"\u003eA temperature and humidity data logger with an OLED display\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 gesture‑controlled LED cube using accelerometer input\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe board works with all standard Arduino Nano shields and 5V sensors. It is programmed via the Arduino IDE after installing the CH340 driver (available for Windows, macOS, Linux). Common pairings include breadboards, jumper wires, ultrasonic sensors, and servo motors.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003ePower the board through the Mini‑B USB port or apply 7–12V to the VIN pin. All I\/O pins operate at 5V logic levels; use level shifters when connecting to 3.3V devices. The CH340 chip is auto‑recognized on most systems, but manual driver installation may be needed on older Windows versions. Current per I\/O pin is 40 mA max.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
