The DSO Shell is a DIY kit for the 0-200 KHz bandwidth DSO oscilloscope. It is a perfect kit for the makers in your life!
The display and MCU are now mounted on the same board (mainboard) to avoid using inter-board pin-headers. Feedback from DSO138 users have shown that soldering on the pin-headers are often problematic for many beginners. The analog channel is placed on a separated board which contains most of the components that need to be soldered on. This brings in better separation between the 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 soldered (except a few through-hole components) and factory tested before packing.
The DSO Shell comes with full enclosure. The front panel and the top/bottom brackets are flexible to allow easy user modification.
A rotary encoder has been added to the design as well. This allows parameter adjustment to be much quicker and easier.
The resolution of the DSO Shell has been extended from that of the DSO138. It reaches 5mV/div - 20V/div while DSO138 was only capable of 10mV/div - 5V/div. This allows for much wider measurements to be viewed and extend the applications for the DSO Shell.
DSO Shell kits has all SMD parts on the analog board pre-soldered and leaves through-hole parts for user to install.
DSO Shell runs on a 9V (do not use power voltage higher than 10V!) power supply. Users need to prepare their own power supply as it is not included in the kits. 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.
It is assumed that users have adequate soldering and troubleshooting skills to assemble the DSO Shell kits. Buyers should be advised that due to the nature of this kit we can guarantee the fully assembled product will function; however, we will make as much efforts as we can to reach that goal.
After receiving the kits users are urged to check the mainboard and LCD by applying a proper power supply. Report immediately to your seller or JYE Tech if a problem or damage is found.
For the 15003K kit SMD component soldering skills are required. SMD parts should be installed before all other through-hole parts.
