• Tested board 3 (previously deployed) transmission with irradiance
  • This board would end transmission whenever
• By suggestion of Garrett we removed the V-switch from the board and connected the load voltage from an adafruit charging chip to the board
  • by doing this we are able to bypass our own charging chip and provide power using the adafruit charging chip
  • need to simulate sunlight fluctuation using the lamp

• Parts on board 5 were desoldered off of the decommissioned board 4
  • We suspect that some of these parts were damaged after desoldering

• Debug populated board 5
  • Some parts need to be swapped out
  • Continuity test of board 5
• Create another spot on csv file for measuring voltage at XBee pin
  • Will be used to look for ghost voltage
  • Nathan said we might not be able to do it : Correction we might be able to use it
  • Debug LED flag : turn on led and keep it on after Ghost voltage is perceived
  • ADC6 might be able be a input chart
• Look into power switching of charging chip
  • Tryston said that between 4.3 - 4.5V the board would be powered by the battery instead of the solar panel
• Use debug LEDs to set a flag if the board is not transmitting
  • What do we flag?
  • Make the XBee drop a packet using the light
  • match XBee power drop to switch between solar panel and battery power
  • Look into board behavior when light is on full blast
• Populate a new board as soon as new parts come in
• Take off vswitch and connect to the charging chip load
  • LEDs should act the same as the adafruit charging chip LEDs
• Populate a board with charging chip
• The VBATT connection is directly connected to the MCU
  • Incorporate a voltage divider to that connection.
• Add decoupling capacitor to the vswitch connection (may or may not matter)
