Hello.

Item: https://www.pololu.com/product/2450
Why in PCB in pic https://a.pololu-files.com/picture/0J6050.1200.jpg?52a232f9359079ae6100fa3680fc9eff installed resistor 9,1KOhm but in pic https://a.pololu-files.com/picture/0J6718.1200.jpg?2eb34786bc2b9fca7e468980d3f04d43 resistor 6,8 KOhm ?
This resistor function ?

Hello.

This is a complete module manufactured by Sharp, and we do not have any information about what components like that resistor do. Our expectation is that all of the modules will meet the specifications described in the datasheet, even if some component values differ between units.
