Well I thought as that regulator was getting hot it was toast so soldered up a new Mixtel board with a new zero.
Yet when I connect the zero's I2C pins to the pico 2 I2C pins the RTC I2C lines are lost, take off the zero I2C pins and the RTC is seen. I even got around to putting 4K7 pullups on with has made no difference.
