DIY STC15F2K60S2 for design

Innovation points: 1. Use arcs for layout to make the laid out board more showy (the hardware may not be good enough, but the board must be showy); 2. Provide eight separate VCC and GND for some simple microcontroller designs You can draw power directly from the board; 3. Provides the OLE screen needed for most designs, and three buttons, one of which is a reset button and one is an external interrupt button; (when using the OLED screen and buttons Be careful not to conflict with the extension pins) This is an older work originally made, with an NRF added to it. In this picture, a resistor is used to reduce the voltage for the NRF, but this is a bit easy to damage the NRF and is not practical. So I removed it from this version.
