This is an enclosure for the
FG085 function generator kit from JYETech available on
Amazon and
Sparkfun.
This does not include the FG085 kit, just the 3D printed enclosure. The FG085 kit (that is obtained from either Amazon or Sparkfun) does not include an enclosure, just the front and back plates.
This enclosure can be installed on your separately purchased FG085 by removing the FG085 back plate and sliding the enclosure over the PCB board. Then, re-install the back plate.
