Goals
Review progress on current projects.
Action items
Supplemental BPS
Reverse relay coil suppression diode
Simulate the circuit
Larger relay to switch output (Up to 9 A load)
Switch to microfit connectors
Add an LDO for the reference voltage
Steering
Move decoupling capacitors closer to the ICs
Rearrange Schmitt triggers/signals to reduce the number of traces on the bottom layer
AFE
Tent vias
Label each pin on the connectors (especially voltage taps)
Charger Interface
Add keepout layer around board
Use a trace for 12 V instead of the long polygon
Put the capacitors before the crystal for U1
Replace SPI testpoints with a 5 pin header
Move Q1 closer to U5
Rotate C20 180 degrees
Move trace from P7 to P3 to top layer
Move LED3 to not cut the relay 12 V polygon
