Core Board Resources

Onboard 50MHz crystal active, provide the system clock

Provide standby clock pad (need to provide the required clock on the back of the PCB board by yourself)

Used for 1117-3.3V voltage regulator chip, CPLD operating voltage

Decoupling design, the use of a large number of decoupling capacitors

Provide 5V DC power outlet

Provide USB power supply

Red power indicator

Self lock button switch

A system reset button Reset, as the user input button

All IO leads through the 2*20 pin, 2.54mm space

All IO PIN numbers are clearly marked, and the use of the process is not always look at the schematic diagram of the I/O pin corresponding, very convenient
