Hi,
We've got about 20 x Teensy 4.1 in daily active use in an automotive/24v environment (industrial mobile plant). Each Teensy is connected to the 24v vehicle supply via a OKI-78SR 5V and decoupling capacitors. Both CAN interfaces are connected via 2 SN65HVD230D drivers.
We're seeing some reliability issues, approx. 1 Teensy is failing per month - so a MTBF of about 8000 hours which doesn't seem very good.
I'm guessing that the vehicle 24v supply is fairly harsh and I don't have enough supply conditioning to protect the Teensy board.
Can you recommend best practices that I should be following to keep the boards alive?
Best regards,
Jason
