TIDA-00489: Backdoor access and new sensor

Part Number:TIDA-00489

Hey guys,

I am using the TIDA00489 board and I am making a new version for the circuit board layout. In the new version, I am thinking of a few changes, two I want to discuss with you.

1. I want to remove J3 together with R14 and R15. In my code, I have already removed the backdoor access and the pin definition for DIO_3.
   1. Do you think this might be a problem, like a current drain or something like that?
   2. Do I have to configure this pin DIO_3 at all to minimize current consumption?

2. As the production of the sensor IRS-B210ST01-R finishes soon and Murata is not planning to continue producing comparable SMD sensors, do you know any sensor (preferable SMD), which could substitute this one having similar performance and requirements to minimize the necessary changes?

I hope you guys can help me out once more.

kind regards
