Product Description:
The LGT8F328P Development Board is a high-performance, pin-compatible alternative to the Arduino Nano 3.0, designed for users who need more precision and functionality than the standard ATmega328P. Built around the LGT8F328P-U MCU, this board delivers enhanced processing performance, higher analog resolution, and a variety of advanced peripherals — all while maintaining full compatibility with Arduino IDE and Nano shields.
With a 12-bit ADC (8 channels) and a dedicated 8-bit DAC output, it allows for more precise analog measurements and smoother signal generation. It supports both 3.3V and 5V logic levels, can run at up to 32MHz, and integrates advanced features such as PWM dead-zone control, computing accelerator (DSC), and a unique chip ID (GUID) for secure applications.
Whether used for analog sensor projects, precision control systems, or general embedded development, the LGT8F328P Nano offers better resolution, faster performance, and wider voltage tolerance — all in a compact Nano form factor.
