+### Serial mode
 If you have a transmitter that can support serial communication with the board then you need to wire up the board appropriately. There are three versions of the module and the steps are slightly different.
 
 Check which module you have and based on the pictures below.  If you purchased the module after June 2016 then it is likely that you have a V1.1 type module. If you have purchased the version with case it is likely that you have a V1.2 type module.
