Power Supply Considerations Single battery operation Pi (capacitor-input) filter will be required to filter unwanted frequencies introduced by motors Multiple operating frequencies Level translators for digital logic I2C translator for microcontroller-camera link Multiple destinations PCB for main components PCB for camera
Microcontroller Considerations Bulk/Ceramic bypass capacitors 0.1 µF 0.01 µF Dual-resistors and a capacitor for reset circuit Located opposite the power supply components Power supply for microcontroller will be the nearest power component Level translators will be located near the header pins for their associated components (camera & autopilot) Voltage regulators for all components will be located away from the microcontroller
Miscellaneous Considerations “Fuel” gauge Potential for high current operation around the “fuel” gauge components Passive circuit components are required to correctly sense the lithium-ion polymer battery levels Independent connections to each of the battery cells (3 in total) Xbee-PRO The location of the XBee header will affect RF signal quality
Miscellaneous Considerations (continued) Camera The camera will not be located on the main PCB Headers will be required on the main PCB The camera will require level translators for all logic signals SD Card Mounted on the main PCB No level translation required
