Schematic and layout designing is done on the Eagle PCB design software. The design is made taken into consideration of the different requirements of the ICs used in the board. The important design aspect  to be taken care of is to choose the value of VCAP of the microcontroller. The value of the VCAP is to be choosen between 470nF and 1uF. If the value is not choosed carefully then the whole design wont work. The schematic and the layout files are uploaded in the files section.

The layout is checked and each layer is verified using Gerbview software. Then it is given for the fabrication. After the PCB is received, the components are soldered in the main PCB and are checked for any short connections.

The development board and the working of the peripherals is tested using the codes which are uploaded. The programmer used is ST-Link V2 and is programmed using the SWIM port . The compiler used for the codes is IAR Embedded Workbench.
