  • Could anyone confirm which shield pins should be connected to use this with a Netduino in I2C mode? ‘Member #226770’ and N8VHF both seem to have puzzled it out; Member #226770 suggests connecting GPO1 to +3.3v and grounding GPO2 to enable I2C mode. Unfortunately, it appears that GPO2 in this shield is connected to a pull-up resistor. Do I have to eliminate the pull-up before grounding GPO2? Or is setting GPO1 and GPO2 not even necessary?

No public wish lists :(
