5. EPCS16, onboard serial FLASH memory, for storing code
6. Power indicator
7. LEDs
8. Reset button
9. nCONFIG button: for re-configuring the FPGA chip, the equivalent of power reseting
10. Power switch
11. 50M active crystal oscillator
12. 5V DC jack
13. JTAG interface: for debugging/programming
14. FPGA pins expander, VCC, GND and all the I/O ports are accessible on expansion connectors for further expansion
15. LED jumpers, short the jumpers to drive the LEDs

Note:
CoreEP3C5 provides JTAG debugging interface, yet does NOT integrate any debugging function, a debugger is required.
Mother board and programmer/debugger in the photos are NOT included in the price.
