This is case for GM328A universal tester module. Module is powered by standard 9V battery or via external 5.5 mm connector on a side. It has 3 pairs of external connectors for frequency measure, square wave and PWM output and for voltage measurement.
There is also additional rocker switch and green LED for power status indication on the same side as power connector. Original SMD LED has been unsoldered from board and replaced by 5 mm green THT LED extended by 10 cm long wires.
Case can be hanged on a wall though two holes in the back or sit on a wall holder (as seen on pics). Wall holder and display frame are additional parts. Case will work fine without them.
WARNING: Dimensions of GM328A module may vary! I had to re-drill two holes on my particular board, because they were drilled 1.5 mm from their original position and rotary encoder was shifted a little bit too. Always measure first, print later!
All parts are printed from PLA. Display frame and rotary button has 0.1 m
