There are sixteen user LEDs on-board, D1-D8 connected to MCU port P25 and D9-D16 connected to MCU port P16. To disconnect the LEDs from the MCU, it is possible to remove RN3 (D1-D8 at port P25) and RN2 (D9-D16 at port P16).

It is also possible to connect a standard LCD module with backlight to connector J6. With the potentiometer RP1 the contrast of the LCD can be adjusted.
