Hi all, i've did my first electronic design (plase bear in mind i'm a mechanincal engineer), the teensy shield I designed contains one canbus trascriver one volteage regulator for power supply and one IR sensor MLX90621ESF.
The purpose of this cirquit is to measure the tyre temperature accoss the tire with and stream measurements to the canubs.
Before ordering the boards i would love is somebody can have a look to the board routing to see if i did some mistakes ! My main concern is about the pullups for the I2C.
The MLX sensor it's calibrated and works a 2.6V while the micro is at 3.3V, i've attached the pulups to 3.3v but i'm not sure thats the right way nor if it's harmfoul for the sensor if the high state of the communication lines is higer than the power supply.
Thanks ! View attachment Teensy_Can_Mk1.zip
