  2. Main Parts Microcontroller Accelerometer Battery and Power Components: 2 cell Li-ion charger 12 V step-up 5 V step-down 3.3 V step-down 2 Screw Terminals for Battery Connection Connectors: 1 – 6 pin JST for GPS 1 – 4 pin JST for WI-FI 4 – 2 pin JST for Temp Sensors 2 – 3 pin JST for RPM Sensors 1 – 2 pin JST for Throttle Position 1 – 2 pin JST for Break Position 1 – 6 pin JST for Steering Angle Sensor 2 – 2 pin JST for Throttle Input to Motor Controller 2 – 9 pin Serial Com Ports for Motor Controller 1 – USB connector for Atom

  3. Layout Overview Power Digital Analog Headers Connectors

  4. Layout • Keep noise from the step-up and step-down converters away from analog components • Get headers close to signals of interest but away from noisy power subsystem • Use single point connection for power and ground to different areas • Route a dedicated analog reference voltage line and filter with RC network
