The Longruner DSO138 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 DSO138 uses mostly through-hole parts. The heart of DSO138 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. Features of DSO138: Analog bandwidth: 0 - 200KHz Sampling rate: 1Msps max Sensitivity: 10mV/Div - 5V/Div Sensitivity error: < 5% Vertical resolution: 12-bit Timebase: 10us/Div - 500s/Div Record length: 1024 points Built-in 1KHz/3.3V test signal Waveform frozen (HOLD) function available NOTE: 9V DC power supply required. Not included. Package included: 1 * DSO138 DIY Digital Oscilloscope Kit 1 * Probe 1 * User Manual(English)
This is Welded(Assembled), can use directly.
DSO138 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.
This DSO138 MCU has been pre-programmed and no re-programming required.partially open-sourced.
