2. Initial Main Board PCB Layout

3. Initial RF Board PCB Layout

4. 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

5. 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

6. 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
