GW12 Basestation

Largely based on 2011 designs but changing to the beaglebone platform.

Beaglebone Hardware Mod

Ice-cape 1.0 modifications required

• Connect ground plane to bottom of Battery potential divider
• Sort out labels so they appear - change layer maybe?
• Add keepout to molex connectors
• increase size of big inductor footprint & add keepout
• Bolts for beagle
• Increase poly fuse size
• footprint for eeprom for cape
• orientation markers for
  • LED
  • Pol caps
  • All Chips
  • All diodes
• Move beagle diode so doesn't clash with inductor
• Fix DMG6602svt footprint issue
• Change 100uF output cap on 5V PSUs to match 3V3 PSU
• Add VCC Tool LED
• Add Beagle control LED
• Add compass? Decided against due to huge amounts of metal
• Fix JTAG header
• Sort out noise on 3V3 PSU
• switched outputs from beagle for USB power controll
• remove cap on beagle reset as it causes instability of reset button
• Diode so beagle can be powered externally without it bleeding into rest of board?
• Add RTC to beagle

=Ice-Cape 1.1 modifications

• clash between msp-rst and bolt
• clash between 12v0 and bolt and beagle
• bottom right beagle hole

MSP Softare to write

• EEPROM Test
• Temp Test
• Time Test
• Accel Test
• output test
• LED test

MSP Software to check

• Job no roll over Actually a problem with counting number of jobs- job numbering was fine
• EEPROM size - now double

Linux Software to check

• Change of power settings

TODO

• Check clock accuracy
• Check ADC using external vref
• Check powering: PASS
  • GPS PASS
  • GPRS PASS
  • Wifi PA PASS
  • Low power 5v load PASS
  • Beagle PASS
• Check Fuse blows PASS
  • 12V PASS
  • 5V PASS
• Check Temp sensor PASS
• Check BattV sensors
• Check current sensors
