DSO138 oscilloscope DIY Kit

DSO**8 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 DSO**8 uses mostly through-hole parts. The heart of DSO**8 is a Cortex-M3 ARM processor (STM*2F**3C8) from ST. It uses 2.*-inch TFT LCD (**0 X **0 dotmatrix, **2K 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.

DSO**8 kits are solded in two configurations. One is with all SMD parts pre-soldered (PN: ****3K). The other is with only the main IC (the MCU) pre-soldered (PN: ****4K). The latter serves also as a SMD soldering training kit. For both configurations the MCU has been pre-programmed and no re-programming required.

DSO**8 is partially open-sourced. This opens the possibility for users to add different features or develop new applications on the hardware

Major features of DSO**8:

• Analog bandwidth: 0 - **0KHz
• Sampling rate: 1Msps max
• Sensitivity: *0mV/Div - 5V/Div
• Sensitivity error: < 5%
• Vertical resolution: **-bit
• Timebase: *0us/Div - **0s/Div
• Record length: ***4 points
• Built-in 1KHz/3.3V test signal
• Waveform frozen (HOLD) function available

Please note that a 9V DC power supply is required to run DSO**8. Power supply is not included in the kit
