I/O resource interface: the main chip resource IO all leads, and on the board marked with clear pin number, 2.54mm standard interface
Reserved three rows of expansion of PCB and leads to each of the IO, 2.54mm spacing, can be self welding headers, rows of seats, or test for measuring point, very convenient
Self lock button switch
All power input and output, are added to the tantalum capacitor, all the main chip 3.3V, 1.2V are added to the 104 tantalum capacitor, to ensure the stability of power
