DSO Shell (DSO150) Oscilloscope DIY Kit

Compared to DSO138, the new DSO Shell has similar bandwidth with significant improvements in structure, mechanical, and operation. The sensitivity has been extended in both directions : 5mV/div – 20V/div (DSO138: 10mV/div – 5V/div.
Display and MCU are now mounted on the same mainboard to avoid inter-board pin-headers.
For better separation between analog and digital circuits, the analog channel is on a separated board.

Without the analog portion the mainboard is actually a general-purpose control board. The mainboard is fully installed (except a few through-hole components) and factory tested.

DSO Shell comes with an easy to modify enclosure. Rotary encoder makes parameter adjustment quick and easy.
Power supply (not included): 9V (< 10V!) standard 5.5mm/2.1mm DC plug or 2-pin connector (0.1" pitch)
Adequate soldering and troubleshooting skills required.
