1. DSO150 Shell has similar bandwith as previous versions though it contains significant improvements in structure, mechanical, and operation.
2. Display and MCU are now mounted on the same board (mainboard) to avoid using inter-board pin-headers. Feedback from users has shown that soldering on the pin-headers is often problematic for many beginners. Analog channel is placed on a separated board which contains most user install parts. This brings in better separation between analog and digital circuits. Without the analog portion the mainboard is actually a general purpose control board that can be used in many other applications. The mainboard is fully installed (except a few through-hold components) and factory tested before packing.
3. DSO Shell comes with full enclosure. The front panel and top/bottom brackets are flexible for easy user modification.
4. Rotary encoder has been added. It makes parameter adjustment much quicker and easier.
5. The sensitivity of DSO Shell has been extended in both directions and is higher and wider now. It reaches 5mV/div --- 20V/div while it was only 10mV/div --- 5V/div prior to this version.
6. DSO Shell runs on 9V (do not use power voltage higher than 10V!) power supply. Users need to prepare their own power supply since it is not included in this kit. The power jack on the mainboard accepts standard 5.5mm/2.1mm DC plug. Alternative 2-pin connector (0.1" pitch) is also provided for convenience to connect to different power sources.

Important Notes: It is assumed that users have adequate soldering skills and troubleshooting skills to assemble the DSO Shell kits. Buyers are advised that due to the skills of the user are involved in the assembly, it is not guaranteed every kit will end up being a working device. But we will give the builder as much help as we can to approach that goal.
