What I did this week:
- Finalized my two PCBs: the constant current supply board and the LED & modulation circuit board.
- Met with Claire & Sid to review all our boards in a team setting, and address each other’s concerns.
- Helped Claire with updating layout of the camera PCB. Specific changes made:
- RMII & DCMI interface layouts: streamlined for signal integrity
- Added 50Ohm impedance constraint and termination on the clock line from MCU to the PLL chip.
- Replaced RJ-45 jacks with JST connectors to save space.
- Added color indicator LEDs.
- Changed the form-factor of the board to fit into an existing waterproof enclosure scavenged from TartanAUV.
- Made 3D models of our PCBs and integrated them into the mechanical CAD of available waterproof enclosures.
- Worked on Ethics assignment.
- We are running a few days behind on ordering the boards, but we will be able to make up this time. We are being extra careful to ensure that there is no hardware bugs.
