“Great sensor - but the address pin when cut appears to be floating and not tied to ground as it should be according to the datasheet. This means that it can't be run reliably on the 0x1E address without adding a pull-down resistor to ground from the address pad, or pin 7 on the chip.”
“Great little board but beware!! I was trying to hook up two of these breakouts on the same i2c bus using the two different addresses and they would not operate together. It turns out that the address pin SA0 (pin 7) on the LSM303D chip is left floating on this board when the track is cut to change the address to 0x1E. So if you connect the two devices the same i2c bus, the address pin can float up to a high value and reverts to 0x1D. I have had to solder a 4k7 pull-down resistor to ground on the right-hand side of the two address pads. This solved the issue.”
“Brilliant. If you need serious real time feedback this will deliver the goods. Even with Python this is blindingly fast. I'm gonna crack on with my drone project now I have this on board. ("on board"... geddit ??)”
