Assemble, test, align and power-up DSO138, Open-sourced Oscilloscope DIY kit

Just purchased a Open-source Oscilloscope DIY kit DSO138, with surface mount components soldered. Here how I assembled it in 2 hours.


After assembled, check voltage on TP22. Make sure it is arround 3.3V. Then short JP4 and install LCD module.


Notice: This video recorded after my final tested, so JP4 have been shorted at beginning. Actually, you have to keep it open after 3.3V on TP22 confirmed.

After the kit worked, align the 0V line and calibrate the probe.





For details and update of the DSO 138 DIY Kit, read Users Manual on the website.

Tested with Arduino Due generated sin wave.

Open-sourced DSO (Digital Storage Oscilloscope) DIY kit - DSO138

Interesting open-sourced digital oscilloscope DIY kit, DSO138, think about buying one. But I can't find the source in the web-site, and instruction to flash the firmware!

DSO138 was designed as a training oscilloscope kit. It contains only the basical 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 dotmatrix, 262K colors) as its display element and displays nice and clear waveforms. Detailed assembly instructions are provided in combination with troubleshooting guide and schematc. Source codes are also available to allow user to add their own features.

DSO138 kits are solded in two configurations. One is with all SMD parts pre-soldered (PN: 13801K). The other is with only the main IC (the MCU) pre-soldered (PN: 13802K). The latter serves also as a SMD soldering training kit. For both configurations the MCU has been pre-programmed and no re-programming required.

DSO138 is partially open-sourced. This opens the possibility for users to add different features or develop new applications on the hardware.

Major 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
