Initial Main Board PCB Layout
Initial RF Board PCB Layout
Special Layout Considerations Sensitive ATD 6 IR sensors surrounding the entire perimeter 2 Ambient light sensors in front RF Daughter Board Requires a .4” ground plane around all sides 1.2” clearance on all sides around antenna Small Area/ Highly Populated Main board smaller than 3”X4” hexagon Basic Layout Guidelines 10/12 mils trace/space Mostly surface mount components
Micro Layout Considerations Passive Components Bypass capacitors close to power and ground No external oscillator considerations (internal clk) Difficult Routing Connects to all components 360 degrees Placement is critical Headers/ Jumpers Headers for ICSP and RF daughter board Jumpers to disconnect ICSP pins from circuit
Power Supply Layout Considerations Multiple Voltages 3.3V regulator powering micro, sensors, and RF 8.4V battery powering LEDs and motor Power Lines Separate analog, digital, and high power 50mils traces and/or ground plane Passive Components Decoupling and bulk capacitors
