DSO Shell (DSO150) Oscilloscope DIY Kit

DSO Shell (DSO150) Oscilloscope has similar bandwidth as DSO138 but contains significant improvements in structure, mechanical, and operation.

Display and MCU are now mounted on the same board (mainboard) to avoid using inter-board pin-headers
Main board can be used as a flexible general purpose controller
Comes with full enclosure. The front panel and top/bottom brackets are flexable for easy user modifications
Rotary encoder has been added which makes parameter adjustment much quicker and easier
Sensitivity has been extended in both directions and is higher and wider than DSO138, reaching 5mV/div — 20V/div

Important Notes

It is assumed that users have adaquate soldering skills and troubleshooting skills to assemble the DSO138mini kits. It is not guaranteed that you will end up with a working device. However, we make as much efforts as we can to approach that goal.

After receiving the kits users are urged to check mainboard and LCD by applying proper power supply. Report immediately to your seller or JYE Tech if 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.

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 the kits. The power jack on the mainboard accepts standare 5.5mm/2.1mm DC plug. Alternative 2-pin connector (0.1" pitch) is also provided for convenience to connect to different power sources.

Product updates

April 8, 2018:

Firmware upgraded to version 113-15001-113 with bugs fixed and minor improvements, download the latest version.
Analog board has been upgraded to "F" version (schematic). A protection resistor (R20) was inserted in the input to avoid short caused by couple switch.

December 5, 2017:

Firware upgraded to version 113-1501-110 with many useful improvements, download the latest version.
Product is now CE certified.

June 10, 2017:

Some modifications have been made to the product to enhance robustness. The changes are detailed below. The new main board PCB version is 109-15000-00E (the older one is 109-15000-00D). The new analog board PCB version is 109-15001-00E (the older one is 109-15001-00C). These are the documents that reflect the changes.

Analog board changes: Updated version: 109-15001-00E (E version)

Regulators were added to increase immunity to power supply noises.
The two capacitor trimmers were changed to SMT package.
J3 in the old desigen (C version) was removed. Because slots have been made on the main board this pin-header is unnecessary for access to the trimmers.
U4D in C version was removed due to the availability of AV- regulator.
U4A in C version was removed due to firmware improvement in trigger algorithm. As result, this analog board requires the support of firmware version 113-15001-060 or later.

Main board changes: Updated version: 109-15000-00E (E version)

Added protection resistors to signals SENSEL0 - SENSEL3 and CPLSEL.
Two slots were made to the PCB for access to capacitor trimmers on analog board. [Photo]
