PIP Board Design #7

Closed ecic2002 closed 1 year ago

ecic2002 commented 2 years ago

PWM, I2C, & Power Distribution Board -Refers to the board which was hand soldered together last year. Holds the IMU and I2C to PWM chip, as well as PIC microcontroller if implemented. Also provided as power and signal delivery to the servos. -Design dependent on: -Consider hardware/components already available in EE labs at Mines. -Make room for leak sensor, barometer, and all listed below. -PCA9685 will be on board -Fit new form factor -Similar connectors as last year to facilitate everything.

Board needs to contain: From/To Jetson: -3.3v Rail (from) <-We might not need this -5v Rail (to) -Gnd -I2C SDA -I2C SDL -Interrupt pins

From 5v Convertor -5v Rail -Gnd

From 12v Convertor -12v Rail -Gnd

Header for IMU -I2C SDA -I2C SDL -Gnd -5v Rail?

Output to Thrusters x 8 -Gnd -PWM Signal

Output to Servos x 6 -5v Rail -Gnd -PWM Signal

Output to Barometer -I2C SDA -I2C SDL -Gnd -5v Rail?

Output to Leak Sensors -Interrupt Pin to Jetson -Gnd -5v Rail?

Output to Light Tube/Other Power -12v Rail? -Gnd

PCA9685 -5v Rail? -Gnd -Supporting Electronics -I2C SDA -I2C SDL

? - To be confirmed

In the interest of time/budget, this year we will stick to using PWM to control the thrusters instead of DSHOT. The pic microcontroller does not need to be included in this years PCS board.
