DSO138 was designed as a training oscilloscope kit. Simplicity in structure and easiness in assembly/operation are the main targets of its design. For these purposes DSO138 applies mostly throughhole parts and the heart of DSO138 is a CortexM3 ARM processor (STM32F103C8) from ST. It also uses 2.4inch TFT LCD (320 X 240 dotmatrix 262K colors) as its display element that will display nice clear waveforms. Detailed assembly instructions are provided in combination with troubleshooting guide and schematic.
This DSO138 kit has all SMD parts presoldered. The MCU has been preprogrammed and no reprogramming required.
