13805K Longruner DSO138 Open Source 2.4＂ TFT Digital Oscill
Longruner DSO138 Open Source 2.4" TFT Digital Oscilloscope Kit 1Msps with Probe Assembled vision (Welded) (Assembled Version)
This is Welded(Assembled), can use directly.
This oscilloscope was designed as a training oscilloscope.Circuit is simple , reliable , inexpensive.
With automatic, regular and one-shot mode , easy to capture the moment waveform.
Adjustable vertical displacement, and with instructions.This opens the possibility for users to add different features or develop new applications on the hardware.
It has been pre-programmed and no re-programming required.partially open-sourced.
The oscilloscope is full assembled ,not DIY KIT!
It contains only the basic oscilloscope functions with no fancy features. Simplicity in structure and easiness in assembly/operation are among the main targets of the design.
For these purpose it uses mostly through-hole parts. The heart is a Cortex-M3 ARM processor (STM32F103C8) from ST. It uses 2.4-inch TFT LCD (320 X 240 dot-matrix, 262K colors) as its display element and displays nice and clear wave forms. Detailed assembly instructions are provided in combination with troubleshooting guide and schematic. Source codes are also available to allow user to add their own features.
