The minimum hardware is introduced: the system board
1. Development board can power supply or USB line simulation system, and the USB power for download, can also external power supply (8 to 12 V);
2. The board IO mouth all derivation, power supply with feet, convenient also lead to expand;
3. Plate carrying eight LED tube, can make water, and when the lamp experiment function indicator;
4. With four independent key, to do the experiment and interrupt the buttons.
5. With the indicator when power, light bright;
6. With the ISP interface and JTAG interface can be your ISP can also download JTAG simulation or download;
7. With a reset button;
8. 3.3 VV, and with 5 V transform chip for outside enlarge experiment can provide 3.3 V and 5 V power;
And with standard:
1. The minimum the system board x1
2. The minimum the system board learning CD x1; (including the principle diagram, procedures, the development software, and reference learning material)
