Hey Louman! That was just a test board, and I don't have any more. It also had some minor design flaws, but I'm starting to think that the real problem may have been the lack of shielding on the current sensor. The LEM is designed to tolerate a noisy environment, but Freyguy found an interesting application note that shows you need a little mu-metal shield around the base of the bus bar, covering the sensor or you can get significant errors.
