Hi everybody,
I need to connect Garmin Lidar to a Teensy 4.1 via I2C. The lidar specification says it operates on 5V so I presume this are also its I2C levels.
Any suggestion on how to connect it to a Teensy 4.1 which operates on 3.3V ? Do I need some level converters or a naive connection should work since the Lidar is an input on the SCL and an input/open-drain (?) on the DAT and therefore doesn't pull any signal to 4V? (I am have no clue).
If a level converter is required, references to ICs or even better small modules that do that will be greatly appreciated.
Also Garmin recommend a 680uf filtering capacitor. Is it ok to attach such a large capacitor to the 5V output of the T41? Will that be safe to the teensy and the usb attached computer?
Thanks.
