  1. SHU: The Running Companion Katie Klacik Brian Baumgartner Dan Strauss Kyle Anderson

  2. Quick Project Overview • Uses GPS to record distance run • Stores Data on SD card after run completed • Displays information to user in an easy-to-understand format

  3. Power Supply Circuit 3 Optical Encoder GPS Receiver SD Card R/W Speaker Input Buttons General Block Diagram LCD Screen 15 1 PA/PM/PB 1 SCI 1 1 1 SCI 2 MCU 5 1 PWM 0 PB/PT 1 PAD PAD 2

  4. Power Supply Block Diagram 5.0 V (150 mA current requirement) 4.35 V 5.0 V Battery Charging IC (Select) LDO LDO Boost Battery (3-4.2 V) 3.8 V (25 mA current requirement) Wallwart (5 V) 3.0 V (25 mA current requirement)

  5. PCB Layout Considerations • GPS positioned as far as possible from the battery and power supply circuit to limit noise • Bypass capacitors close to parts • Short traces between Rx and Tx lines for SCI • Try to keep the LCD trace lengths close to the same • Try to keep the design small and compact while leaving enough room for traces and spacing • Include headers (especially necessary to check MCU-LCD connections)
