 The COG connectors C1 and C2 interface the EV-GEAR-EXPANDER1Z board with MCU Cog.  The connector carries all the GPIO signals from the MCU Cog board. The pinout details are given in the [[resources:eval:user-guides:ev-cog-ad3029lz:cog_hw_userguide#expansion_connectors|expander connector section in EV-COG-AD3029LZ wiki]].  The COG connectors C1 and C2 interface the EV-GEAR-EXPANDER1Z board with MCU Cog.  The connector carries all the GPIO signals from the MCU Cog board.

-<note warning>**If any application is not working on MCU COG connected to a EV-GEAR-EXPANDER1Z board, check for the connectivity from MCU COG to EV-GEAR-EXPANDER1Z. If it is found that there is no connectivity, the one of possible reasons could be, accumulation of dust on the Expander connectors C1 and C2. To resolve this, clean the connectors with isopropyl alcohol or any solvent. +<note warning>**If any application is not working on MCU COG connected to a EV-GEAR-EXPANDER1Z board, check for the connectivity from MCU COG to EV-GEAR-EXPANDER1Z.

 Improper connector mating can also result in the loss of connectivity between MCU COG and EV-GEAR-EXPANDER1Z, make sure that shunts installed on COG are not obstructing the connector mating.    Improper connector mating can also result in the loss of connectivity between MCU COG and EV-GEAR-EXPANDER1Z, make sure that shunts installed on COG are not obstructing the connector mating.
