Error on the SEN0224 Gravity LIS2DH board

Hello,
Please note the INT1 and INT2 silk screen labels on your Gravity LIS2DH board (SKU: SEN0224) are swapped!

Furthermore the 6-pin header containing TP1 and TP2 (test points for INT1 and INT2 signal, respectively) on your board is not shown on your documentation. Since the schematics and layout documentation (on your website and digi-key) do carry this information, users of your board can only rely on the silk screen labels, which are wrong.

I have lost hours of work trying to experiment and debug both hardware and software, before discovering this error.
It seems I wasn't the only one. Here are other people who wasted time due to your label error:

(scroll to the bottom of the discussion to find the conclusion:
“turned out that Gravity LIS2DH kit has wrong labels on it. they just inverted INT1 & INT2!!")

Please correct your documentation for the SEN0224 Gravity LIS2DH board to stop other users from encountering this problem.

Thank you,
Gil Elgez

I am so sorry for the wrong label, we have asked to change the printing of the board, really sorry for the mistake.
