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.
