E-fuse EN/UVLO pin pulled down too far to enable the chip at 1.2V for off-nominal, board does not power on. Just change a resistor and redo calculations.
Do we want to get rid of interrupts?
Set priorities for sensors
Improvements
Don't know how much more it needs/can do. Already crowded
Increase efficiency by redoing layout.
SHTC3 not good in software. Already have other temp sensors. More ambient reading than TMP117. Also does humidity (not needed)
Need to verify theres a difference with ambient reading. Check accuracy compared to other sensors
Don't see need for it to be replaced, but could shop around for interesting sensors. Covered bases with what could be measured in ICs.
A lot of things we can throw on that are nice to have. Think of other interesting sensors we can do.
Noticed that BMP581 is available and can replace BMP388. Low power consumption, higher accuracy and similar pricing
Look into MS5611 as a replacement to MS5607
Investigate using a 9DoF IMU instead of a 6DoF
Radio Module
UART Debug line labels are mismatched
Ethernet LEDs not attached to anything
Copy sensor module Wiznet LED implementation
Need to know it works (software). Needs to function our specifications. Does it work and is it useful in its capability?
Power inductors very difficult to solder by hand, recommend fab house assemble them on future revisions
5V and 3V3 rail voltage drops proportionally with load, up to a ~0.4V drop at 3A this was due to faulty load tester readings, module functions as expected
Wiznet LEDs disabled only by desoldering
Jim suggests targeting above nominal voltage for 200 mV response to voltage drop?
Bulk capacitors causing shorting issues, root cause still unclear
