Channel selection[edit | edit source]

Channel selection is performed by connecting the given pin to ground. The one closest to the edge is "BX". When grounded, BX=1, otherwise BX=0. Note that a solder blob will ground the channel to the rail near the via.


For example, if you want to use 2390MHz, you would add a solder blob across the second pin from the "audio in" below (labeled 2450) and remove the solder blob from the pin to the furthest right (BX).
