Rev A Issues

[brghena]

• U6 doesn't have a pin 1 indicator

[brghena]

• C27 is either the wrong part or the wrong pads
• Some silkscreen reference designators are the wrong orientation by the nRF

[brghena]

• C23, C24, and C28 need orientation markers on the PCB

[brghena]

• Need to purchase headers for the Electron too (should be added as an attribute for the part)

[brghena]

• Need power and ground probe points on the board
• It would be nice to label the individual sensing types on the silkscreen (i.e. the Audio, Light Sensor, BLE, etc.)

[nealjack]

• SD_MOSI, SD_SCLK testpoints need to be flipped onto back of board. (their silk circles are on the wrong side)

[brghena]

• Think about moving most of the passives to a single side of the board

[adkinsjd]

• Connect SD_ENABLE signal to the electron

[nklugman]

• breakout remaining gpios

[nklugman]

if possible route prefilter audio to a free adc pin Decided this isn't necessary - just the breakout.

[nklugman]

if possible make gps fix led visible after box is Moved to software issue

[nklugman]

• add prefilter audio test point

[nklugman]

• add at least some electron pin labels for orientation

[nklugman]

• add gnd and vcc test points

[nklugman]

make sure that temp is included in the mpu driver Moved to software issue

[brghena]

• 60 Hz antenna with non-inverting amplifier (40-100 mV peak-to-peak on a good wire)
