Product details This MS51FB9AE / N76E003AT20 Development Board combines a high-performance 1T 8051-based microcontroller with a full feature set and ready-to-use hardware interface. The microcontroller offers high clock speed up to 16 MHz (or 24 MHz in some variants), integrated Flash memory, SRAM, ADC, PWM, serial interfaces, and low-power modes. The board includes USB or UART connectivity for easy programming and debugging, power regulation for 2.4 V–5.5 V operation, standard headers for GPIO expansion, reset and user buttons, and built-in indicators. Thanks to its rich peripherals (UART, SPI, I²C, multiple PWM channels, ADC), it is ideal for embedded control, industrial automation, IoT, sensor hubs, motor control, and educational platforms. Users can write code in standard 8051 environments or modern IDEs and deploy quickly.
