Push for internal design review, December 3, 2021

Everything is done. Just have to connect the circuits to the MCU and we are all set.

Finished the stepper motor schematic. Just need to add pins.

Also forgot to box the level shifter circuit.

Forgot to add the datasheet for the N-channel MOSFET.

Added level shifters for I2C channel. The plan is to put all IMU's (including the Boom tip IMU) on the same I2C channel because we do not have enough I2C channels on the MCU to go around. Thermopile will have it's own channel. The stepper motor schematic is the only circuit left in the design. Then I can integrate everything and begin the layout process for the PCB.

Almost done. Just designed a LDO for 3V to power the Thermopile. Need to design level shifter for I2C devices since all devices need to operate off of 3.3v logic.

Rearranged the layout of the schematic sheets. Circuits are the same.

I edited the Thermopile schematic. It will be on board so there was no need for a connector. We could add some test points in the prototype to read I2C.

this is thermopile initial schematic
