I am confused by the chip markings on two different examples of the Pololu compass/accelerometer carrier (LSM303DLH #1250 and LSM303DLM #1273), purchased a few months apart.
One chip (product #1250) has 4 lines: 4XGK / HM55 / 043 / MLT while the other (product #1273) has SLJB / 303DH / 143 / MLT The boards appear to be otherwise identical with respect to markings. I was finally able to sort out which was which by checking my order history, and discovered that the chips are slightly different, most importantly with regard to axis orientation. However, if I had taken both carriers out of their shipping bags I would now be at a loss as to which is which, as the chip markings make no sense to me.
Given that Pololu products like these are being discontinued/replaced and/or changing product numbers so quickly, it would be helpful if a Pololu product number could be put on each board, so customers could keep track of their inventory.
Thanks, Jim Remington
