A nice interface capable of running two load cells (only one through the solderless terminal block) to a proper I2C serial interface (rather than the more common proprietary serial interface). Unfortunately it is a fixed single address so running more than two load cells will be more difficult (a limitation of the chip). One bit of thoughtlessness in the layout loses it a star: I wanted to cut the solderless terminal off to make it smaller and because I was going to have to solder the second cell on anyway. This could have been easy and simply a matter of cutting the end off the board with a dremmel. Sadly there is one surface-mount resistor unnecessarily mounted on the TB end of the board which needs to be preserved.
