The following sections provide details on expansion connectors and switches on the carrier board that allow 

users to expand the Open-Q™ 212A functionality. Users should ensure the devices they connect to the 

carrier board meet the specific operating range.   

 

3.8.1  Configuration Dip Switch – S10 

DIP switch S10 locates on the top side of the OPEN-Q™ 212A carrier board. This 8-bit switch allows user to 

config various system functions and boot options. See table below for function of each switch position.
