PCB layout divided into 4 functional groups Digital Analog Power Supply Motor control

Analog components Sensors and the wireless transceiver isolated from high power components to reduce the effect of EMI radiation on the sensors This helps because the Electro magnetic field intensity decreases exponentially with distance in air.

Microcontroller PCB specifications Decoupling capacitors placement Additional capacitors for additional noise Components of MCLR kept at 6mm Trace length between the ICSP connector and ICSP pins kept to minimum

Motor Control and Power Supply EMI due to high switching nature of the currents can be reduced by decreasing the current loops(placing the components closer). The heat generated by the converters is taken of by the components themselves as both the regulators have large exposed ground pads for better thermal connection to the PCB.
