Nudiuhis C8051F330 Development Board MCU Chip C8051F330 Development Board Development Board

+5V, 3.3V and GND are all led out with pins, which is convenient for users to do extended experiments. All IO pins of the microcontroller are led to the two rows of pins of the core board and marked. Power supply method: Use the USB power supply cable or external 5V power supply or downloader to power the core board through the JTAG port. The frequency of the external crystal oscillator used on the board is 22.1184M. Users can use the internal crystal oscillator of the microcontroller or the external crystal oscillator. There are 3 buttons on the core board, one system reset button and two user buttons, and there are characters on the circuit board.
