Manufacturer Description


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 sold in two configurations. One is with all SMD parts pre-soldered (PN: 13803K, replacing 13801K). The other is with only the main IC (the MCU) pre-soldered (PN: 13804K, replacing 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.
13803K and 13804K are newly released improved models with following upgradings:
Significantly lowered noises. Comparing: [NEW] vs [OLD] in measuring the built-in test signal.
Waveform can be saved to and recalled from non-volatile memory.
Enhencement in Test Mode with auto short-circuit detection capability.
Supports two types of TFT controllers (ILI9341 and ILI9325/9328).
DSO138 is partially open-sourced. This opens the possibility for users to add different features or develop new applications on the hardware.
