Anyone confirm or deny this....I think the scl and sda lines are crossed over on the diagram - they certainly do not agree with the PCB (which works) AND the memory expansion addresses look as if they are displaced by one, Pin 1 chip 1 is A0, on the actual baord it is tied to +ve as you would expect. The chips only have 3 address lines which all make sense IF you move the bits to the right, ie chip on datalogger board, address =000, chip 1 on expansion board, address=001, next one =010, next one =011 etc.
Truth please!!!!
