* B, D, and E positions contain through hole pads that can be used for two components to be connected
in parallel.
†
F and G positions contain a surface mount 0
Ω
resistor; you
must
remove the resistor to use the position.
If you remove your custom components from the F or G position, you
must
reinstall a 0
Ω
resistor.
