/Component Test Board/
- This directory is for the KiCad project dedicated to the Component Test Board.
/Board Redesign/
- This directory is for the KiCad project dedicated to the IRIDIUM 9523 carrier redesign.
- Within this is Iridium Carrier (2). * files. These files are the Eagle project files, and the previous Senior Design Team's (Team SCUBEE) schematic and PCB files being used for reference.
- The redesigned project is being placed within /KiCad Project/, and this directory contains the Eeschema and PCBnew footprints and symbols created for the purpose of this board.

Find a replacement for the LT3959 Boost circuit
Verify the final status of JP4 (Sim Card Enable); whether it is tied to the 5V line or the SIM enable line coming from the IRIDIUM 9523
Verify the status of JP1 (mode switch pin of IRIDIUM) if it's tied to GND or to the status of JP2.
Verify the status of JP2 (mode switch high-voltage jumper); if it is tied to 3.3V ISENSE line or 3.3V bus.
Verify the status of JP3 (RF enable reference voltage); if it is tied to 3.3V ISENSE line or 3.3V bus.
Determine whether S1 (the RF enable switch?) is necessary in end-product.
Verify the status of JP5 (the VCCA power source of U3); is it tied to 3.3V ISENSE or 3.3V bus.
Determine if JP3 (the +3.3V, +5V, and bus power voltage 3-pin header) is required in end-product.
Decided whether the SAMD21 is adequate, or should we transition over to the SAMD51 for memory / I2C capabilities.
Determine whether S2 (the microcontroller reset switch) is necessary in the final product.
Identify which test points are essential / desired.
