Solar Panel Preparation
Splice or Adapt?
The first verison of the solar charger came with a 4mm DC barrel jack on it. On older
versions (4mm) it would come with a converter cable.
If you have a newer v2 charger (June 2013+), connect a 2.1mm Terminal Block
Adapter (http://adafru.it/369) onto the panel using basic wires, or a 1.3mm to 2.1mm
adapter cable (http://adafru.it/2788) then plug that into the 2.1mm adapter. This is the
fastest method
If you have an older v1 charger, you can use the terminal block method above OR cut
the adapter cable in half and splice the 4mm connector onto the panel. The panel will
plug right into the board but its more work.
Voltaic Panels with 1.3mm Connectors
Grab one of our adapter cables, it will let you plug in the solar panel
directly (http://adafru.it/2788)
