This week I focused on the verification documents for the PCB and the power consumption analysis for the system. The power consumption analysis was completed to the point where the verification documents needed. Further work on the verification documents will be done after some preliminary firmware is written so that we can test bring up software. Next week will be dedicated to firmware and getting estimates on battery life given the power consumption analysis.
Harper’s Status Report for 3/6
This week we finalized the PCB designs and submitted them for approval to the TA. Furthermore, I helped Stefan with the mechanical design of the shell so that we can plan for the physical spacing of the PCB in the overall design. Lastly, I started on the operational verification documents for the PCB so that we can begin on the functional use before the PCBs arrive.
Harper’s Status Report for 2/27
This week I worked on the PCB design and BoM with Stefan to make sure our circuit had all the components we needed and each IC would be kept within operating conditions. I then routed the PCB and sent it to PCBWay for approval. I also started on the Power Consumption Analysis. A preliminary look at it was well within reason at <5mA.
