 =====COG connectors=====
-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|expander connector section in EV-COG-AD3029LZ wiki]].

-<note warning>**If any application does not work with MCU COG and EV-GEAR-EXPANDER1Z connected, check for the connectivity from MCU COG to EV-GEAR-EXPANDER1Z. If it is found that there is no connectivity, one possible reason might be accumulation of dust on the expander connectors C1 and C1. To solve this, clean the connectors with isoprophyl alcohol or any clean solvent. Air blewing the connectors also works to solve this problem**</note>
+<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, one of the 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.
+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.

 =====Gear connectors=====
 The connectors D1 and D2 can be used to connect a Gear. Gear is an addon application board which can be a custom build to serve the required application.
-<note important>The gear must have the connector ([[https://www.digikey.com/product-detail/en/hirose-electric-co-ltd/DF17(4.0)-60DP-0.5V(57)/H11146CT-ND/1036112|DF17(4.0)-60DP-0.5V(57)]]) to interface with D1 and D2 connectors.</note> The pinout details for D1 and D2 are same as that of COG connectors ( C1, C2 [[resources:eval:user-guides:ev-cog-ad3029lz:cog_hw_userguide|expander connector section in EV-COG-AD3029LZ wiki]]).

 =====Arduino Uno headers=====
 The headers A1, A2, A3, A4 and A5 support the shields that are Arduino Uno compatible. The following table captures the signals connected to the headers
