Hi freshbird

1.my test is on Edison breakout board ,and my levelshift is TXS0102.

For i don't know much about ediosn arduino kit and BSS138. Maybe you can compare and find some differences.

 

2.Some advices

make sure your sensors can work well seperately.

make sure levelshift works well,oscilloscope can help a lot.

if pull up sensors are already in the levelshift  there is no need to add extra  pull up resistors for sensors in my case.

 

let me know if it helps~

 

Regards

ma jiayao
