Peripheral Units
LED Diodes
The board has 8 LED diodes, which make the simplest interface between the system and the user.
This is especially useful for the beginners, who want to manipulate or debug their program with
different hardware configurations. The diode turns on after grounding of the associated Ldn (n = 0
–
8) pin.

DataFlash Memory
Board have external DataFlash
AT45DB041B
memory with 4MB space. Memory is power by diode,
which decrease voltage. Is a possibility to power without that diode, correctly from supply source by
short jumper 3V3 placed near memory.
